One of the best named basins in Yellowstone - Biscuit Basin, and it's very active geysers. In fact the one in the foreground erupted every 5 minutes covering us in warm steamy water each time. This combined with the cloud cover made taking photos a bit of a challenge to say the least, so I gave up after this one!
