“It was the first of November, and I was regretting having missed my chance to summit the last time I went up the Glen Boulder Trail. It was hard enough in the summertime, when the ground was clear, but today there was already a surprising amount of snow clogging up the trail.“
– from 4000s by 40
This page captures images from the experiences in Chapter 30 of 4000s by 40—the final climb. I had come a long way in my journey, but I was surprised that completing the 4000-footers didn’t bring a feeling of euphoria. Instead, it brought a sense of peace. If you want to know more about what the 4000-footers are like, you can read more [here]. And to go along with the photos below, I’ve also added a quick retelling of events, along with quotes, to give you a small sense of what you’ll find in the book. Enjoy!
Back on the Glen Boulder Trail
By most people’s standards, I had climbed Mount Isolation. Exhausted on my previous attempt, I missed the spur trail that leads you an addition twenty vertical feet to the summit. I was so close, I practically climbed it. But I have a real problem with not being able to tell the whole truth. If I was twenty feet short, then I didn’t fully climb it, and I needed to correct that. So, even though I swore I wouldn’t finish my 4000-footer quest on Mount Isolation (largely because it sounded like a lonely mountain), I set out on November 1st, a little less than a year from when my adventure began, to conquer the last remaining mountain on the list.
I wished there was a better alternative, but the most efficient way to climb Isolation meant that I would need to tread the same path I stomped before. First up the Glen Boulder Trail to the Davis Path, and then down the dreaded Rocky Branch Trail. Initially I thought about skipping the Rocky Branch Trail and simply backtracking from the summit to Glen Boulder, but the snowy conditions changed my mind. It was a long slog, but I didn’t care how long the day took me. I was going to enjoy this moment, and nothing—not even the Rocky Branch—was going to ruin it.
Summit Success #48: Mount Isolation!
I finally made it! When I reached the spur trail that led to the summit, I was in disbelief. How, with all this climbing, could I have missed this? It just goes to show, no matter how much you do something, you can, and will, continue to make mistakes. Fortunately, at the summit is a survey marker to confirm the spot. Hallelujah!
“There was no grand epiphany here, no sudden wisdom revealed. Only the recurring thought that I was glad that I had stayed true to myself and did what I had set out to do. I could look myself in the eye.”
If you don’t see this, you didn’t make the summit!
The Dreaded Rocky Branch
The day didn’t go quite as planned. Mountain climbing tends to be that way. By the time I reached the junction of the Rocky Branch, I knew which way I was going, but I was way behind schedule. Had I chosen to go back the other way, up the Davis Path leading towards Mount Washington and Glen Boulder, I wasn’t sure how long it would take. I didn’t have much energy left and certainly didn’t feel like ascending anymore. I was ready to go down.
Night fell. I was ready for it when it came because I imagined it long before it did. For old times’ sake, remembering my climb on Garfield, I took a photo of me looking scared, but I wasn’t. And of course, if I had to, I could always belt out some Tesla songs to make myself feel more at ease. But everything was copacetic. I didn’t even mind the Rocky Branch so much as I ambled in the dark. I was at peace, and the difficulty of the trail dissipated with my temperament.
When I finally reached the trailhead, I turned up the road to walk the 3.5 miles back to the Glen Ellis parking lot where my truck was. I had no intention of hitchhiking the distance today. As a soft rain began to fall, I donned a light shell and walked back without any urgency. It was cold and raw out, but I was comfortable with little protection from the elements. Even when the rain turned to snow, I left my heavy jacket in my pack. I felt warm enough.
“The list is nothing more than a prescription to help us get out there and find ourselves again.”

Exploring & Peak Resources – Mount Isolation
Mount Isolation (4,004′) lives up to its name—remote, quiet, and often overlooked due to the long miles required to reach its summit. While it’s among the shortest in elevation on the AMC 4000-footer list, it’s among the most mentally and physically demanding because of the lengthy approach from any direction.
