Audio from the Artist Paintpots in Yellowstone. The hiss in the background is the constant float of steam from the ground along with the regular release of pockets of air from these odd little spitting mud holes. Pretty cool to see and producing a very unique sound. Not sure if it'll be useful for anything, but it was too cool to pass up. Again, sorry for the short duration; there was a lot of traffic and wind there. Recorded on a DSLR and edited in Audacity. Production-Now.com - Shout-outs welcome.
