Johnstone Peak via Pioneer Cabin Trail near Ketchum, Idaho: This Hike for Henry Brown
Navigate off Pioneer Cabin Trail's beaten path to walk on Johnstone's rocky east ridge for a massive view of Idaho's rugged Pioneer Mountains. We returned to this hike we dedicated to the memory of our great friend Henry Brown.

There are several ways to get up to Johnstone Peak, an almost 10,000-footer near Ketchum, Idaho. Its summit is in view for most of the way when approaching it from the north on Pioneer Cabin Trail where the final 1,000-foot gain involves route-finding on a faint, unmarked and rocky trail. At the top, we met two people who had ascended from Bear Gulch, to its south. It's an inspiring peak to us, not only for the breathtaking views of the main Pioneer Mountain crest, but also for remembering our friend Henry Brown. In 2016, we dedicated this hike to Henry because of his love for Idaho's wilderness (This Hike for Henry Brown).

A faint trail extends towards Johnstone's east ridge after the saddle at Johnstone Creek Trail is reached, just before its descent. The westward 1.6-mile climb to the summit first traverses the shady north side of the ridge, and then because of the northern steep chutes, it switches to the south side, going over a few talus fields. The summit is one large stable talus pile. Having done this hike a few times before, we know now to stay close to the ridge; when it begins to pull you to the south, keep west at about 260 degrees. The trail passes over a large talus field of a "pseudo peak"; and upon mounting it, you see Johnstone's summit across yet another talus field.

O! Lovely talus field - at least it is stable!
Some gorgeous textures and colors
Just when you are done climbing high points, the real summit is still on the horizon (Johnstone on right)
Except for a few stunted trees, the summit is bare and exposed, but it rises far above everything else, marking the area between the Wood River Valley and famous Mt. Baldy's ski mountain to the south and central Idaho's peaks to the north.
Four years ago, after the first dusting of snow, Fred and I stood on Johnstone's summit with a sign proclaiming "This Hike for Henry Brown". Henry, in his mid-50's had passed in August from lung cancer. He was a West Point grad, avid outdoorsman and excellent bow and rifle hunter, and had spent his last years in Hailey, south of Ketchum in the Wood River Valley. It was especially hard for Fred to lose his great friend, one that had shared his passion for wilderness and taught him valuable hunting skills. When Henry had moved back to Idaho, there was hope for many hikes in Idaho's beautiful wilderness. But these never happened and we were reminded that life can be cut short. More than ever we know that we are lucky to be able to walk the forests and rocky summits of Idaho and look forward to the next American West adventure.
In 2016, as we were on Johnstone's summit remembering Henry, an eagle flew high above, a symbol of Henry's spirit. And this time again as we were descending, an eagle, soaring effortlessly above the northern side of the peak made us stop as it passed by and out of sight. I had said the next time we summited Johnstone, we would be looking for an eagle. Once again we saw one, and felt Henry's presence.

About this blog
Exploration documentaries – "explorumentaries" list trip stats and highlights of each hike or bike ride, often with some interesting history or geology. Years ago, I wrote these for friends and family to let them know what my husband, Fred and I were up to on weekends, and also to showcase the incredible land of the west.
