Mt. Hebo Traverse – 09/19/2023

At the start of the year I scheduled a week of vacation in September just in case our August backpacking trip to the Wallowa Mountains didn’t work out. That vacation worked out so I had a free week while Heather needed to work. When that happens I tend to look for longer hikes in areas where we’ve already been together.

For this outing I chose Mt. Hebo planning to hike up and over from Hebo Lake to South Lake and back. We’d been to Mt. Hebo twice before, most recently in 2015 (post), but never to the actual summit or as far as North & South Lakes. I parked at the Hebo Lake Day Use Area and walked through the campground to the signboard at the start of the Pioneer-Indian Trail.

Hebo Lake

From the trailhead it’s four miles and approximately 1500′ to the meadowed plateau of Mt. Hebo. The lower portion of the trail includes several interpretive signs.
Despite it being the end of Summer the forest was a lush green.

So much green.

The trail crosses several roads along the way and near the one mile mark an equestrian trail joins from the left. All crossing and junctions were well signed.

The equestrian trail. In 2015 we made the mistake of turning onto it briefly.

Love the mossy trees.

This more recently thinned section was full of ripe red huckleberries.

Crossing Road 14 near the 3-mile mark.

There was a small section where there had been a lot of blowdown that had been removed.

At the 4.4-mile mark the trail crossed Road 14 again and traversed a hillside above several tributaries of Three Rivers.

This late in the Summer there was no water.

Another dry crossing.

The trail made another crossing of Road 14 just 0.4-miles later then rounded a wide ridge. Near the 5.5-mile mark I reached the start of the steep descent to North and South Lakes where we had turned around in 2015. This time I continued on.

After descending three quarters of a mile North Lake became visible through the trees, or I should say the dry lakebed of North Lake became visible.

The trail stayed above the lakebed and forked. The right hand fork led to Road 14 along the lake shore while the Pioneer-Indian Trail continued to the left.
This was the only official junction that was not signed.

With no water in North Lake I stuck to the Pioneer-Indian Trail and hoped that South Lake wouldn’t be the same. After an initial climb over a ridge the trail gradually descended arriving at South Lake 1.3-miles from North Lake.

Road 14 – again.

South Lake through the trees.

There was water in this lake (and one car in the campground), so I followed the half mile trail around the lake.

The trail around South Lake.

After completing the loop I headed back along the Pioneer-Indian Trail.
I really appreciated being reminded that it was eight miles back to Hebo Lake.

I returned past North Lake and began the 600′ plus climb that needed to be made to get back up to the plateau.
I couldn’t really get a good view but there was a nice meadow along the trail between the two lakes.

Oregon grape

Bridge over Three Rivers near North Lake, I almost thought I heard a slight trickle of water here.

Good sized garter snake in the trail ahead.

Normally these snakes slither off into the brush as you approach but this one coiled up in the trail, so I took a long step over it and continued on.

This was the steepest section of the climb up from North Lake.

On the way down I’d spotted two separate flagged trails along the ridge end that appeared to lead up to the plateau. There were no signs but a quick look at the GPS and maps showed a road on the plateau that connected with Road 14. I thought it might be a little shorter to go that way, or at least it might mean a little less climbing because the trail dipped as it passed the dry streams feeding Three Rivers.

Looking up the flagged route.

I turned up the first of the routes that I came to and climbed steeply to the plateau where the tread quickly petered out.

Remains of some sort of old structure were present. The summit of Mt. Hebo could also be seen.

I could see the old roadbeds though so I followed the closest thing I could find to old tread to the first roadbed and turned left onto it.

Mountain ash and maple.

Approximately a third of a mile from the Pioneer-Indian Trail I reached a gate at the end of pavement and in another tenth found myself on Road 14.

I had a choice of turning left or staying straight on Road 14. It would have been about 0.4-miles back to the trail along the left fork, but the map showed Road 14 curved a couple of times while staying straight appeared more direct.
Going the left would have also been the way to North Lake. The road apparently gets narrow and a bit rough beyond this point.

I went straight and followed Road 14 nearly 0.7-miles before arriving at a trail crossing.

I turned right at the trail marker here. As it turned out it wasn’t any shorter at all and I wouldn’t recommend this route due to a lack of tread between the flagged trail and old roadbed and then having to follow Road 14 for so long.

I followed the Pioneer-Indian Trail back through the meadows then, after almost a mile, when it neared Road 14 again I took a short path over to the road to detour up to the summit.

A hedgenettle

I took this left to cut over to Road 14.

I followed Road 14 uphill for half a mile then turned right to visit the former site of an Air Force Radar station (now radio and other towers).

A path near an interpretive sign led out to the former radar site and a view of the Pacific.

Lots of yarrow still blooming at the summit.

I returned to Road 14 and followed it back down to the Pioneer-Indian Trail and headed back to Hebo Lake. It was nearly 3.5 more miles to the lake but luckily it almost entirely downhill and it had stayed relatively cool. I did stop for a moment to talk to three hikers from Corvallis who had originally headed East that morning but realized it was too smokey to be enjoyable, so they’d come West instead.
