The Bumpass Hell (pronouced Bump-uss, not Bump-ass)
is the largest geothermic region in Lassen Volcanic National Park, which covers
16 acres. It has a lot of sulphur vents, boiling water and mud pits. The trail
to get there is easy, but goes over some rocky terrain. It's about 3 miles or
so round trip from the trailhead.
It was named after its discoverer, Kendall Vanhook Bumpass. He lost a leg as the
result of burns that were obtained when he fell into a thermal pool. At the high
elevation where this is located (8,100 feet above sea level) water boils at 198
degrees farenheit. However, the superheated water coming out of the ground is
over 280 degrees farenheit.
