Opalescent Pool And Black Sand Basin Landscape

Black Sand Basin Landscape

I first visited Black Sand Basin in Yellowstone National Park during the evening on the previous day from this shot. It was overcast and getting dark and I didn’t even notice this little side area next to the entry drive to the parking lot. I didn’t see this until I visited the next morning, a lovely, sunny day. I’ve been reading: TravelBrains’ “Yellowstone Expedition Guide” and learned this interesting fact: the trees you see here are dead, of course. The bottoms of their trunks are white because they absorbed the hot water in the area, which is filled with silica in solution. That silica comes out of solution and is what has colored those trunk bottoms. It’s the first step in petrification of the trees. Oh, and Black Sand Basin gets it’s name from the black obsidian sand grains in the area. Cool, huh?
