Yeah, that’s really what they call it—Bumpass Hell. Allegedly named for a cowboy named Bumpass who burned his leg there in the 1860’s.
Lassen Volcano had a major eruption in 1914-1915, but was a national monument even before that.
The hike to Bumpass Hell is about 1.5 miles one way at about 8000 feet. The trail had a few patches of snow on it, and I’m glad I brought my hiking polls for some of the slush/snow traversals. The temperature was around 55 to 60 degrees Fahrenheit and sunny. Great hiking weather.
Other than that, it was a long day of driving—both before and after Lassen. I’m now in Oregon, contemplating getting up early for morning light at Crater Lake.
