Back in 2016 we set a goal for ourselves to hike all 500 featured hikes in William L. Sullivan’s “100 Hikes…” series of guidebooks post. In 2020 we completed the first of these books covering the Central Oregon Cascades (post). We followed that up by completing a pair of books in 2021 starting with Sullivan’s “100 Hikes/Travel Guide Oregon Coast and Coast Range” 3rd edition (post) followed up by “100 HIkes/Travel Guide Northwest Oregon & Southwest Washington” 4th edition (post). Southern Oregon & Northern California was completed in 2023 leaving us with Eastern Oregon.
In 2023 we pivoted from the 3rd edition of Sullivan’s “100 Hikes/Travel Guide Eastern Oregon” to his renamed 2022 1st edition “100 Hikes Eastern Oregon” book. This was to avoid needing to make the tedious drive on horrible roads to Dug Bar in Hells Canyon which had been replaced as a featured hike in the newer edition.
The criteria for checking a hike off our list is to hike a portion of Sullivan’s described hike or, at least visit the main attraction(s) he identifies for the hike. For 67 of the hikes we completed the books described route. For the other 33 hikes various factors contributed to us not completing every option of each featured hike. For some we started at a different trailhead, others had portions of trail(s) closed when we visited, and several had additional options that we did not do.
Of the five regions Sullivan breaks his guidebooks into, the Eastern Oregon region is the largest and most diverse. The area covered in this book includes hikes in Oregon east of the Deschutes River in Central Oregon and from Klamath Falls (western most hike) east to the Idaho border. There is however one hike in Washington west of the Deschutes across the Columbia River from The Dalles, OR. It also includes one short option in Idaho (eastern most), one featured hike in California (southern most) making it his only book with hikes in more than two different States. The northern most hike is not the one in Washington. That honor belongs to the Wenaha River near Troy in NE Oregon.

The hikes involved several wilderness areas: Oregon Badlands, Mill Creek, Spring Basin, Strawberry Mountain, North Fork John Day, North Fork Umatilla, Wenaha-Tucannon, Eagle Cap, Hells Canyon, Monument Rock, and Steens Mountain. Missing from this list are the Black Canyon (post) and Gearhart Mountain (post) wilderness areas which had featured hikes in earlier versions of Sullivan’s book that we’d completed, but were removed in the 2022 edition due to wildfire damage.
In addition to the 11 designated wilderness areas there were hikes in two National Monuments, the John Day Fossil Beds National Monument in Oregon and the Lava Beds National Monument in California, and one National Volcanic Monument, the Newberry National Volcanic Monument.

*The Juniper Hills Preserve is owned by the Nature Conservancy and had been closed to public entry in 2023, so we were unable to hike the trails. We parked and walked to the gates to take photos. If they ever reopen it to the public we will go back.
Completing our featured hike goals provided a sense of relief. While we thoroughly enjoyed all of the hikes, and the Wallowa Mountains became our favorite destination in Oregon, we had begun to put pressure on ourselves to finish. That pressure had begun following the September 2020 wildfires that ravaged parts of the Central Cascades and left many trails closed for years. We had just finished the featured hikes in that area earlier that year and realized how close we’d come to having to put our goal on hold. In the grand scheme of things reaching 500 featured hikes is irrelevant but having worked on it for several years it was something we didn’t want to abandon. We will gig deeper into that in a later post covering finishing the 500, but it’s nice to have the urgency to get to specific places removed.
Setting the goal did provide us with an excuse to visit parts of Oregon that we’d never seen before. While we were checking off the 100 featured hikes we stopped at over three dozen additional spots including eight previously featured hikes. There are still numerous trails left for us to explore so we will almost certainly be heading back to Eastern Oregon from time to time to see new sights and possibly revisit some familiar ones. Happy Trails!


Beatys Butte to the SW.
Rain to the SW as well.



Threemile Creek could be heard but not seen through the thick brush.
Lupine
There was a post but no sign at the junction.
Wickerstem buckwheat
The Pueblo Mountains (
Clouds and rain showers to the SW.
Threemile Canyon
The faint Huffman Trail.
Alvord Peak in the center distance with Pueblo Mountain to the far right.
Closer look at Alvord Peak in the center.
Still a little blue sky to the NW.
Not sure where the fog below came from but it was on a mission to beat us up to the plateau.
Here comes the fog and some rain.
Just moments later.
And here is the fog.

The final pitch to the plateau.
Cairn at the end of the trail.
Exploring is possible as long as you remember where you came up.

Arriving back at the junction with the Threemile Creek Trail.

Curlycup gumweed
The trail crossed and at times used dry creek beds and also crossed Threemile Creek several times.
The easiest crossing of Threemile Creek. Several of the others were not obvious until I pushed through the brush and then the footing was often tricky due to large, slick rocks needing to be navigated (at least in order to stay out of the creek).
On the trail, I think.
Elderberry
Hard to tell by the photo but this puffball was a little bigger than a softball.
I wouldn’t really describe the area as a meadow but I was 0.9 miles from the junction.
Looking down at the meadow and post/snag (lower right) from the rocks.
Sometimes the trail was really only identifiable by which junipers had had limbs cut.
The drop to the creek here was approximately 2′ and the pool in Threemile Creek was fairly deep making this crossing a bit of a challenge not to slip and fall in.
Aster

Sullivan’s map showed a “Bart Simpson Rock” which we believe was this one.

Other structures from the ranch.
The gravel road is in good shape but you don’t want to drive any faster than about 10mph so you don’t miss any wildlife.
Fawns
Common nighthawk
So many red-winged blackbirds.
Hawk (northern harrier?) in a field.
More fawns and birds.
Finch?


It disappeared in the grass moments later.
Another hawk
Sandhill cranes in the field.

Crossing the dam.
Kiger Gorge (
Kiger Gorge
Blurry due to distance but there were several deer at the far end of the reservoir.
Another long shot, a western grebe.
Not certain what this bird was but it dove into the water a couple of times.
The deer, some ducks, the western grebe and a cormorant were all that direction.
It also appeared that some rain was on the way.
Recrossing the dam.
Pheasant family
There were at least 5 deer out there.

We climbed this rise on the ridge and continued on the top for a bit.
Looking at the rocky cliffs that would force us to the west.

It’s not a desert trail without bones.

Sculpted rock along the ridge.

Thought this might be an arrowhead or at least something that was used for a tool of some sort.

A hazy Pueblo Mountain (and more of the Pueblo Mts.) from the high point.
Cairn #15 is on a small rock outcrop near the saddle at center.
Cairn #15 (at least we think).
Cairn #15 below from the cairn #14 coordinates, it appears that cairn #14 may have been at least partially dismantled.
Oh great, more uphill.

There were a number of tiny grey birds in here, at least two in this photo.
A bigger bird, but not by a lot.
A wood nymph
This was a huge boulder along the trail. At least two small junipers were growing out of it.


The stone house is too low to even stand up in but it was enough to stake a claim to the land.

Levi was one of 9 Prinveille Hotshot firefighters who perished on Storm King Mountain in Colorado fighting the South Canyon Fire. This hit home for me having gone to school with one of the 9, Bonnie Holtby.

Wildhorse Lake from near the end of the bench.
We were a little disappointed to see just how late we were for most all of the wildflowers. I don’t know how much the drought this year affected the timing or if it blooms that much earlier in SE Oregon but the remains of what looked to have been an excellent display were all we were left with.
A few stone steps began the steep descent along the stream.
A few of these little yellow flowers were still in bloom.
This was a mass of pink monkeyflower a few weeks ago.

We missed this nest on the first pass. It was about 30 yards off the trail.
We also missed this Nuttall’s linanthus blooming along the trial.

This was a very pretty butterfly that for some reason the camera just didn’t want to focus on.
