California Trip August and September 2005

John J. and Barbara R. Thomas

Lassen Volcano National Park

Bumpass Hell

       Bumpass Hell is a hot spring area on the flanks of Lassen Volcano. A short hike took us up over a ridge and then downward to the springs. It is probably called "hell" because of the steaming pots and the sulpherous smell.

Part way up the trail to Bumpass Hell, you get a nice view of Brokeoff Mountain,
a small remaining piece of the rim of a huge caldera.
