Boundary Trail (Johnston Ridge - Hummocks Trailhead) Professional Review and Guide

"Lupine and fireweed grow from the pumice-covered landscape. The path soon descends along the south side of the ridge in full view of Mount St. Helens, the Pumice Desert and the grassy benchlands along the North Fork Toutle River Valley. Small huckleberry and elderberry bushes grow up between the stumps. Penstemon blooms here in July and in August pearly everlasting blooms appear. Blacktail deer as well as elk frequent this spur ridge.

You will probably see their tracks on the trail and may get a glimpse of them moving away at your approach. Castle Lake is in view ahead to the southwest. Castle Lake was formed by the eruption of Mount St. Helens in 1980 and the resulting mudflow that dammed the South Fork Castle Creek. After crossing the spur the trail heads northwest. Soon Coldwater Lake, another lake that was formed by the eruption, comes into view ahead."

We did this one as an out and back, starting at the Hummocks Trailhead and heading up to Johnston Ridge, then returning. This was a GREAT choice, because going the other way would have added greatly to the difficulty! We started in the early morning, and it was a bit foggy, but by the time we got to the Loowit overlook, it had lifted for the most part, and we got a great view of the Mountain and crater. We went the rest of the way to Johnston Ridge, and sat and watched the video as a rest, then hiked back down into the valley. It was quite a bit warmer on the way down. The trail itself is mostly a single file path and is a bit steep in places, but we found it to be well marked, and in very good shape. We had a very enjoyable time, and there were lots of places to sit and talk, and take in the view of the incredible change the mountain made in a surprisingly short amount of time. We got back very tired from the hill climb and descent, but we had a great time.
