One item on my "bucket list" is to visit every National Park in the United States. So far, 2 are in the book. Please check out my website for all my shots from Yellowstone and Grand Teton National Parks.
Looks like liquid mercury. I remember the mudpots of Yellowstone many years ago ... never did get a decent shot. This is fantastic in B & W ... plus the textures are interesting. Faves!
