Ascent Trip Report

This peak is the highest in the park and is 2.5 miles up to the summit and almost 2000 feet. We got to the trailhead about 8:00 and I started hiking about 8:23 AM. There was only one other vehicle in the parking area (and it turned out that person was not hiking Lassen Peak). I definitely wanted to start as early as possible, considering how hot it has been getting here during the mid day.

Anyway, the trail up Lassen Peak is very well maintained and even has display boards at several of the switchbacks and just below the summit. Early on, one must cross some snow banks and there were a few others along the way, but nothing too serious. I will say there was a lot of snow on the mountain still at this late summer date. I got to the first turn and took off my fleece and never put it on again for the hike. This hike was basically switchbacks all the way up to a short (0.2 mile) ridgeline hike to the summit. The trail and switchbacks, once out of the lower reaches, followed a rock wall formation that was formed when Lassen erupted – lava came out of crevices on the sides of the mountain and solidified leaving these jagged rock spires in a line where the crevice was.

Oh yeah, on the way up, as I got closer and closer to the top, the number of Tortoiseshell Butterflies increased dramatically, possibly exponentially. Unfortunately, I do not have a good picture to show you, but they were flying around, armies of them, so many that I started waving my hand to get through them (slight exaggeration). I made it up in about 2 hours, spent about 20 minutes at the summit and made it down in less than an hour. It seemed to me that after every switchback turn on the way down, I met hikers coming up.
