Yellowstone National Park Sights


Biscuit Basin Review

North of Old Faithful, this basin is also the trailhead for the Mystic Falls Trail. The namesake "biscuit" formations were reduced to crumbs when Sapphire Pool erupted after the 1959 Hebgen Lake earthquake. Now, Sapphire is a calm, beautiful blue pool again, but that could change at any moment.
