Volcanic Sounds of the Yellowstone Caldera


On one of my drive-abouts I found myself in Yellowstone National Park. it's a jolly fun place if you like that sort of thing... You know... Buffalo, trees, geysers & such. It pushes a couple of my buttons for sure. Yellowtone has wo many cool sounds that I simply had to record some of them.

Mud pots that go glurp, glurp. Little holes in the ground that sound like they are gargling. Big, deep pools that release giant bubbles of gas.... Caves at the edge of pools that belch forth great volumes of steam and water then the water flows back in for the next show. They must have good writers there for the variety is seemingly endless.

There is a lot of subsonic sound being created at Yellowstone. In some areas you can put your hand on the boardwalk and feel the movement of the ground. When reviewing the recordings I was pretty astounded at how much subsonic stuff there was. Then you are there... after a few minutes your brain adjusts and tunes it out but microphones & recording devices don't do that. So I found it kind of thrilling... That said, I still attenuated it a bit...

I want to go back with a different set of gear. More mics & multi-channel recordings and figure out how to capture that sensation of feeling the ground heave from the great indigestion below.

Low Tide at Soberanes Point, CA
Oct 20, 2020
Once again I found myself at the ocean with nothing better to do than subject my microphones to hostile conditions. I had been driving up and down along the coast south of Monterey looking for the right spot. I was looking for a protected cove-type location. One without a mile-long expanse of sand and giant waves from the deep ocean to come crashing in.

Way in the background, you can hear the distant roar of the surf. This location was about a mile and a half from the open sea and high tide was about an hour earlier.
Ocean Waves at Molera Point

I'm not a surfer, though perhaps I would like to be. I like the ocean. Every time I drive out to the coast there is that moment of the first smell of it. Sometime, if the wind is just right, you can be fifteen miles away when you sense the first hint of salt and seaweed. And then there is the thrill when you rise over the hill or curl around the bend and are presented with the far-off horizon.

This is a full chorus of frogs. They start and they stop and then one starts singing again and others tentatively join in. You can identify certain individuals and different species. it's quite a fun time.

Mosquito Lake... sound like just the place you would want to go to on vacation.
Spring Songbirds, Patterson California
Jun 10, 2016
This is the first field recording it put out for public consumptions. It was recorded the first week of March, 2016 in the Hills east of Patterson, Ca. It was a beautiful Spring morning and I found an acceptable location by a small brook. Birds singing in the area make it a very pretty-sounding location. Unfortunately a gravel truck bame by about every 20 minutes which limited the length of the recording.
