Corvallis Hiking Oregon Willamette Valley

Peavy Arboretum to Dimple Hill – 10/22/2022

We finally saw some much needed wet weather arrive which started to push out the smoke that had caused the air quality in NW Oregon to be some of the worst in the world for a few days. I was more than happy to alter my plans if it meant the beginning of the end of the nearby fires. With anywhere from a 40 to 90 percent chance of precipitation (and the possibility of an isolated thunderstorm or two) the most promising forecast was for the McDonald-Dunn Research Forests north of Corvallis. Heather and I had visited the McDonald Forest four time already, the most recent in 2021 when we attempted to connect the previous three hikes via a big loop from the Sulphur Springs Trailhead (post). Due to some closures for active logging operations we were only able to connect two of the three hikes, McCulloch Peak (post) and Chip Ross Park to Dimple Hill (post). My plan for this outing was to connect the other hike, Peavy Arboretum (post), as well as checking out a few trails in the forest that we hadn’t been on previously.

After checking online to make sure there were no current closures that might affect me I decided to start my day at the Peavy Arboretum’s Woodland Trailhead
IMG_3617

I had left my route for the day fairly open as I wasn’t sure how wet I might get. I knew that I wanted to start by hiking the 0.4 mile interpretive Woodland Loop Trail which began at the far end of the Woodland Trailhead and then I’d planned on making my way to the Lewisburg Saddle Trailhead where I would follow Road 600 (Patterson Road) SW at least three quarters of a mile to a junction with the Ridge Trail where we had turned onto that trail on our 2021 hike (coming from the other direction). I didn’t get many photos on the interpretive loop since the Sun hadn’t quite risen yet and it was fairly dark under the trees.

IMG_3626Starting to get a little lighter near the end of the loop.

After warming up on the sort loop I walked a short distance along the entrance road toward the entrance then crossed the road at a post for the Red Cedar Run Trail.
IMG_3627

IMG_3628

What followed was a 19.2 mile (19.6 including the Woodland Loop Trail) reverse lollipop loop utilizing parts of 29 different trails and roads in the forest, not all of them on purpose. This is a good time to mention that having maps is extremely helpful when exploring this forest, but due to the active management by the Oregon State University Forest Department new trails are occasionally constructed while others may be closed or rerouted (the same for roads). Some trails are also closed seasonally or, as we saw on our previous visit, due to active logging operations. Finally the map/brochure available online from the Forest website, at least as of this writing, does not show all of the existing roads/trails. This was an issue that I ran into late in my hike today. Other online resources such as Trailforks show some of the missing roads/trails but may also omit others. (Trailforks is a mountain biking site so some of the hiker only trails such as the Woodland Loop are not included on their map.) My recommendation is to have as many maps handy as possible and a sense of adventure if you’re going to start exploring the area. I had my Garmin and the Forest map but really wish I had had the Trailforks map with me as well.

Back to my hike though. My route went like this (TF indicates that the trail was shown on the Trailforks map but not on the Forest map.):
Woodland Trail, Red Cedar Run Trail, Peavy Arboretum Road, Maritime Meander Trail, Forest Discovery Trail, CFIRP Trail, Section 36 Loop, Road 550, Road 500 (Nettleton Road), Dave’s Trail, Road 5010, Vineyard Mountain Trail, Road 600, Road 650, Upper Dan’s Trail, Road 650, Road 600, High Horse Trail (TF), Upper Bombs Away (TF), Road 640, Road 600, Ridge Trail, Road 600, Road 580 (Davies Road), New Growth Trail, Old Growth Trail, Road 580, Dave’s Trail, Banzai Trail (TF)*, Road 543, Road 540, Section 36 Loop, Road 540, Calloway to Cronemiller Trail, Calloway Creek Trail, Intensive Management Trail, Pond Trail.

*Instead of the Banzai Trail I had intended on taking the Powder House Trail but this section of the Banzai Trail wasn’t on the Forest Map and I went left when I should have gone right at an unsigned junction.

If that sounds a little confusing it was. As you may have guessed the weather turned out much better than forecasted with only one shower that lasted less than a minute near the end of my hike. I suspected I might be in for a nicer day as I made my way up the Red Cedar and then Maritime Meander Trails.

I took a quiet detour to Randall Pond before hopping onto the Maritime Meander Trail.

I stayed left at trail junctions along the Forest Discovery Trail, crossing Road 510 along the way, then turned left onto the CFIRP.
IMG_3648The trails were well signed in the Arboretum.

IMG_3652

IMG_3659

IMG_3663I had been on the Forest Discovery Trail just under a mile when I reached the CFIRP Trail.

I followed the CFIRP Trail for half a mile uphill across Road 514 and ignoring a spur trail back to Road 510 to the Section 36 Loop.
IMG_3665Road crossing.

IMG_3670The Section 36 Loop junction.

I turned left onto this trail, the first section of trail that I had been on previously, and continued uphill 0.4 miles to Road 550. I left the Section 36 Loop here and took a left onto the road.
IMG_3677Section 36 Loop

IMG_3679A bench along the trail faces this tree.

IMG_3681Road 550 from the Section 36 Loop.

Most of the 0.3 mile road is closed to motorized traffic so Road 550 was fairly overgrown compared to the other roads/trails in the forest but there was still clear tread. I did question my choice though when my feet started to feel the moisture from the grass start reaching my socks.
IMG_3682Looking back down Road 550.

IMG_3683My feet started to dry when I reached the section open to motorized vehicles.

Road 550 ended on a saddle at Road 500 where I again turned left following this road just under half a mile to Dave’s Trail where, you guessed it, I turned left.
IMG_3687

IMG_3691Lots of sparrows, towhees, and wrens were out this morning but most wouldn’t sit still at all.

IMG_3697

IMG_3699Dave’s Trail

I continued to climb gradually on Dave’s Trail crossing Road 590 near the quarter mile mark then dropping slightly to Road 5010 at a 3-way road junction after 1.3 miles.

IMG_3711

IMG_3712A gated road on the left led back up the hill I had just passed under some radio towers while Road 500 was to the right. Road 5010 was ahead on the left heading up Vineyard Mountain.

On our previous hike we’d taken the Vineyard Mountain Trail uphill from this junction (having come up Road 500 instead of on Dave’s Trail) so this time I followed Road 5010. When I reached the radio towers atop the mountain I discovered that we’d completely missed the remains of the 1930’s Dean George Peavy Cabin.
IMG_3714The Vineyard Mountain Trail at the junction.

IMG_3719

IMG_3720

IMG_3722The foundation, fireplace and chimney are all that remain of the former OSU Dean’s cabin.

After visiting the cabin remains I continued slightly downhill on Road 5010 to a post marking the Vineyard Mountain Trail.
IMG_3725

It was approximately 1.5 downhill miles to the Lewisburg Saddle Trailhead where there were a decent number of cars.
IMG_3729Some twisted trees along the Vineyard Mountain Trail.

IMG_3732After numerous tries I finally caught a spotted towhee.

IMG_3733The Vineyard Mountain Trail briefly follows an old roadbed.

IMG_3735The section of trail between the roadbed and the Lewisburg Saddle Trailhead is one of the trails subject to seasonal closures. This section is closed when it is wet enough that you’d leave tracks in which case you could follow the roadbed to the right to Road 500.

IMG_3736Close up of the seasonal closure notice. It wasn’t wet so I continued on the Vineyard Mountain Trail.

IMG_3737

IMG_3739

IMG_3742

At the trailhead I crossed Sulphur Springs Road and passed an orange gate on Road 600 (Patterson Road). After gradually climbing for three quarters of a mile I arrived at a junction with Road 620 on the right. The Ridge Trail started from Road 620 near the junction so I could have turned there and followed it back to the Lewisburg Saddle I would have accomplished my goal of connecting all of our hikes here. The weather was so nice though that I decided to push on and try to reach Dimple Hill.
IMG_3743

IMG_3750Looking back at the towers on Vineyard Mountain from Road 600.

IMG_3753Road 620 on the right.

I stayed on Road 600 for another 1.4 miles (the first 0.6 being new to me) then turned left onto Road 650 at a saddle.
IMG_3754

IMG_3757

IMG_3760

IMG_3762

A tenth of a mile up Road 650 I veered onto Upper Dan’s Trail and made way to the summit of Dimple Hill.

IMG_3771Mary’s Peak (post) with a cloud just blocking the summit.

The view was nice but there were enough clouds and lingering haze to the SE that I was a bit disappointed. Someday I will make it a point to get to Dimple Hill on a bluebird afternoon/evening but for now I settled for the blue sky overhead and headed back to Road 600.
IMG_3773

If I would have had the Trailforks map handy I would have seen that I could cross Road 600 at the saddle and follow it uphill to Road 662 which would have brought me to what is shown on that map as the High Horse Trail. I then could have followed that to Upper Bombs Away but those two trails weren’t on the McDonald Forest map. I hiked back down Road 600 just over three quarters of mile to a trail crossing where I turned left on the unsigned High Horse Trail. (Not sure if that is the “official” name but it is the name on the TF map.)
IMG_3784

IMG_3788The High Horse Trail. Not shown to the right coming up from below is the Upper Horse Trail.

Despite the High Horse and Upper Bombs Away Trails not being shown on my map or Garmin we had taken these on our 2021 hike so I was familiar with them.

IMG_3794Unsigned junction where the High Horse Trail continues to the left to Road 662 and Upper Bombs Away veers right.

IMG_3796Another connector trail on the left coming down from Road 662 to join the Upper Bombs Away Trail.

The Upper Bombs Away Trail can get a little confusing as it switchbacks downhill but the forest along the trail is some of my favorite in the McDonald Forest. There is another well established trail that basically shoots straight downhill and a couple of use trails that appeared to possibly be coming downhill from Road 600. I basically stayed left and/or downhill until I arrived at Road 640 (0.6 miles from the High Horse Trail).
IMG_3797Will the real trail please stand up?

IMG_3798Switchback near Road 640.

On our previous visit we had crossed Road 640 (it was closed between the trail and Road 600 at the time) and followed Lower Bombs Away to the Ridge Trail at Road 620. Since I’d been on that section of trail before and not Road 640 I took the road 0.3 miles back to Road 600 then turned left on Road 600 for 100 yards to Road 620.
IMG_3802

IMG_3805

I hopped onto the Ridge Trail and followed it up and over a knoll to Road 600 near Lewisburg Saddle.

At Lewisburg Saddle I took Road 580 for a tenth of a mile to the New Growth Trail and headed downhill.

After a mile on those two trails I was back on Road 580 which I followed for almost two miles to Dave’s Trail.

I turned left onto Dave’s Trail which paralleled Road 580 for 0.6 miles where it met the road again.
IMG_3865

IMG_3867Blackberries

IMG_3869

IMG_3871

It was here that things got a little messy for me. I was already at approximately 15.7 miles and my plan was to head back as directly as possible. The plan was to take the Powder House Trail on the other side of Road 580 which was the only trail shown on the McDonald Forest map (no trails were on the GPS topo map). When I crossed the road though there were were two trails. One heading slightly downhill to the left and one uphill to the right and no signs on this side of the road.
IMG_3873The proverbial fork in the road.

I went left (I chose poorly) and followed what I thought was the Powder House Trail a third of a mile to a sign with a pointer for the Banzai Trail.
IMG_3874

IMG_3875Madrone

IMG_3878A few clouds starting to move in.

IMG_3877

IMG_3879

The McDonald Forest map showed a small section old road between Roads 562 and 543 as the Banzai Trail which I was not close to according to the GPS. The Trailforks map shows the Banzai Trail starting where I had left Road 580 so my guess is that it has been somewhat recently added. I decided to forge ahead knowing that whatever I was on would eventually hit one of the forest roads that I could use to reach Cronemiller Lake and get back on course. I followed signs when available and after a mile found myself at a road with no apparent signage.
IMG_3880

IMG_3881

IMG_3883The Banzai Trail likely continued on the other side but without a pointer I wasn’t about to find out and turned right here which took me uphill for a tenth of a mile to the Road 560 and Road 562 junction.
IMG_3884

IMG_3885This is the start of what is labeled the Banzai Trail on the McDonald Forest map.

IMG_3887

Road 562 went straight downhill and steeply.
IMG_3888The photo doesn’t do the steepness justice but the trail lived up to its name here.

IMG_3891At some point the road became 543 before reaching a fork where I stayed right.

IMG_3892Another closed roadbed on the left. This is where I stayed right on Road 543.

In another quarter mile I found myself at a 3-way junction.
IMG_3893Road 540 to the left and 541 to the right.

I turned right on Road 541 which brought me to Cronemiller Lake in half a mile.

IMG_3901

IMG_3902

IMG_3903Not that kind of a lake.

I went right around the lake on the Section 36 Loop where for the first time all day a very brief shower passed overhead.
IMG_3904

IMG_3905A few drops hitting the lake.

IMG_3912Kingfisher on the far side of the lake.

IMG_3918

The trail hit Road 540 on the far side of the lake where I turned left and walked back along the lake on the road a short distance to the Calloway to Cronemiller Trail.
IMG_3920

IMG_3921

IMG_3924

I turned right onto this trail following it downhill for 0.2 miles to a junction with the Calloway Creek Trail.
IMG_3926

I turned right and then turned right again a short distance later onto the Intensive Management Trail.
IMG_3931Second right.

I crossed three roads in the next 0.3 miles before arriving at a signboard map at a split in the Intensive Management Trail.
IMG_3933

IMG_3939

I veered right following the Intensive Management Trail for another 0.3 miles to the Peavy Arboretum Trailhead.
IMG_3940

IMG_3944

A 100 yard road walk brought me to the Pond Trail at Randall Pond which I briefly followed before cutting across two roads to the Woodland Trailhead where I’d started almost 7 hours earlier.
IMG_3945

IMG_3947

IMG_3948

In the end the wrong turn onto the Banzai Trail had only added a mile or so to my day and it was trail that I hadn’t been on before so that was a plus. There was enough up and down to put the cumulative elevation gain right around 3000′ feet but none of the climbs were too long or steep. The weather couldn’t have been much better and the trail/road conditions were very good which made a hike like this a bit easier. The amazing thing is that there are still roads and trails that I’ve yet to explore which makes the thought of returning that much more exciting. Happy Trails!

Corvallis Hiking Oregon Trip report Willamette Valley

Bald Hill & McCulloch Peak

Our latest outing took us to the Bald Hill Natural area and the McDonald Dunn Forest. (Hike #48 in William L. Sullivan’s “100 Hikes/Travel Guide Oregon Coast & Coast Range” 4th edition.) This pair of hikes near Corvallis, OR was a recent substitution in our hiking schedule. We were looking for a hike closer to home for the day after attending the homecoming game at my alma mater – Western Oregon University (It was Western Oregon State College back in my day) with my college roommate and his family. My roommate Tim and his wife Erin had already been dating when Heather and I began seeing each other so the four of us had spent quite a bit of time together in those days. We spent all day Saturday reminiscing starting with an alumni breakfast and ending with dinner at Mendi’s Pizza.

We were able to sleep in a little on the day of the hike since the drive was just under an hour and it hadn’t been getting light out until almost 7:30am. We took Highway 99W to Corvallis then turned right (west) onto NW Walnut Blvd for 4.3 miles to NW Oak Creek Drive where we once again turned right. Both of the days trailheads were located along this road and we hadn’t yet decided which we were going to start with. We had been waiting to see what the weather was like. It had been extremely foggy the prior morning and we didn’t want to head up Bald Hill (the shorter of the two hikes) if there was no visibility because the guidebook indicated that it had the better views. The forecast for the day called for patchy morning fog and a 20% chance of showers before 11am, but as we neared the Bald Hill Natural Area .8 miles along NW Oak Creek Dr. there was no fog just some higher clouds so we pulled into the already busy parking lot.

The majority of cars seemed to belong to runners and the rest dog owners. The area offers numerous trails, some paved and some not, as well as an off leash dog area. It reminded us a bit of Minto-Brown Island Park in Salem except there were hills instead of a river.

We set off from the parking area crossing Oak Creek on a footbridge and heading straight out a wide paved path.
IMG_7537

IMG_7539

As the path began to curve through the wetlands Bald Hill came into view.
IMG_7541

The route suggested by Sullivan turns right off the paved path after a half mile passing an old barn on the right. We wound up turning right one path too soon though and found ourselves passing through a field with the barn up on a hill to our left.
IMG_7542

IMG_7546

We followed a faint path up through the field to the barn where we picked up the correct trail.
IMG_7547

IMG_7548

IMG_7549

With the aid of trail maps at junctions we were able to stay on Sullivan’s route climbing .8 miles to the summit of Bald Hill.
IMG_7551

IMG_7552

IMG_7557

For a cloudy day the view was very nice. The first of two benches on the hill overlooked the southern end of Corvallis where trees blazed with fall colors amid the houses.
IMG_7561

IMG_7558

Various fruit trees lined the trail at the summit drawing birds to the area.
IMG_7553

IMG_7564

IMG_7567

The second bench looked to the SW towards Mary’s Peak which was mostly hidden by clouds.
IMG_7566

IMG_7568

After passing the second bench we continued on our loop 1.9 miles passing farmland and more birds on the way back to the parking lot.

The loop was 3.3 miles which was a nice warm up for our next stop which was to be a 9.5 mile loop in the McDonald Dunn Forest with a stop atop 2154′ McCulloch Peak. From the Bald Hill parking lot we continued west on NW Oak Creek Drive following it to the right at a fork after 1.1 miles and continuing to a parking area at the roads

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

gated end. The McDonald-Dunn Research Forest consists of approximately 11,250 acres largely used by Oregon State University for instruction and research. Various trails and roads are open to hikers, bikers, and equestrians although occasional closures do occur due to forestry activities. Despite having checked the forest website the night before we noticed a sign at the trailhead stating that our planned return route (Road 770) was currently closed due to a timber harvest. The route up to McCulloch Peak was open though and there appeared to be a couple of other ways to return using different roads and/or trails so we sallied forth.
IMG_7587

IMG_7590

We followed Patterson Road from the gate just over half a mile to a junction with road 6020.
IMG_7593

Near the junction was the beginning of the Extendo Trail.
IMG_7595

The Extendo Trail is open to Bikes, horses, and hikers from April through October and then to hikers only from November through March. We followed this trail across Oak Creek and then uphill for almost 1.5 miles. Fall was on full display in the forest along the trial with colorful leaves and plenty of mushrooms to be seen.
IMG_7597

IMG_7600

IMG_7601

IMG_7602

IMG_7603

IMG_7606

IMG_7610

Some of that fall color was attributable to poison oak which we were keeping a close eye out for.
IMG_7615

IMG_7616

The Extendo Trail ended at a 4-way junction. To the left was the Uproute Trail which headed back downhill to Road 6020. An unofficial (illegal) path continued straight uphill and to the right was gravel Road 680 and a pointer for McCulloch Peak.
IMG_7619

We followed road 680 uphill to a clearcut saddle with an interpretive sign and a bit of a view to the NW.
IMG_7620

IMG_7621

IMG_7623

IMG_7626

Beyond the saddle Road 680 came to an end at Road 700 where we followed another pointer for McCulloch Peak.
IMG_7629

Just before reaching the junction with Road 770 we got a clear look at our destination, McCulloch Peak.
IMG_7630

We passed closed road 770 1.1 miles from the Extendo Trail.
IMG_7631

IMG_7632

We passed several roads sticking to Road 700 until we reached Road 790 which was also signed Marvin L. Rowley Road (named after the former Forest Manager).
IMG_7639

We reached the summit a little over a mile from Road 770 where a small bench awaited.
IMG_7645

Although it wasn’t wide, the view was nice enough.
IMG_7646

IMG_7648

IMG_7649

After a brief break we headed back downhill. Since our planned return route was closed we decided to look at the map and see what other options we had. First we turned left when we got back to Road 700 following it for a quarter mile to Road 740 which looped around a small knoll before rejoining Road 700 after another quarter mile. Near the end of Road 740 we passed a stump covered with Chicken of the Woods mushrooms.
IMG_7658

IMG_7660

IMG_7664

We then retraced our path down Road 700 to Road 680. At the clearcut viewpoint on Road 680 we spotted a faint Mt. Jefferson against the clouds.
IMG_7665

IMG_7668

We had a choice when we reached the junction with the Extendo and Uproute Trails. We could return on either of those trails or stay on Road 680 and follow it down to Patterson Road. We decided on following the road which swung out to the west for .6 miles to Patterson Road just over a mile from where we had turned off it earlier to take to Extendo Trail uphill. It was a pleasant walk through the woods back to the trailhead.
IMG_7675

The hike wound up being a little over 9 miles giving us a total of 12.4 miles for the day. The trails (and roads) in both of the areas were in excellent shape and the number of options and year round accessibility makes them nice options anytime of the year. They will be on our list of nearby alternatives when we want to get outside but don’t want (or can’t get) too far from home.

Happy Trails!
