115: Lassen Volcanic National Park- Bumpass Hell- Boiling Acid Pool

115: Lassen Volcanic National Park- Bumpass Hell- Boiling Acid Pool

Author: Sound By Nature September 16, 2022 Duration: 1:27:00

This was recorded early on a clear and cold late summer morning at Bumpass Hell in Lassen Volcanic National Park, Shasta County, California. The recording was gathered from the boardwalk near a boiling pool of murky, highly acidic water. The jet like sound is made by the many nearby fumaroles emitting steam and volcanic gases.

Bumpass Hell is one of the most popular geothermal areas of Lassen Volcanic National Park, so I went as early as I could to avoid the crowds. I got there just before sunrise and was able to make this recording before any other visitors arrived. I have only visited this area on warm summer days in the past, so it was really neat to see it on a cold morning when the steam coming from the numerous fumaroles and boiling pools was clearly visible and hung in the air for a long time before dissipating. And the early morning sunlight on the colorful landscape was incredibly beautiful. If you ever get the chance to visit this place I highly recommend going early on a cold morning, you'll be glad you did.

A lot of time, effort, and work goes into gathering these recordings for you, and I can really use your help to provide you with high quality field recordings of natural sound.
