The next stop is Fountain paint Pots where mud bubbles up in colors of blue, orange and pink. Spasm and Jelly geyser. The boardwalk takes you to an overlook where you can photograph many geysers in various stages of activity. This trail also passes some dead trees that are coated with silica, giving them a weird appearance. At the beginning of the drive are dead trees encrusted with mineral deposits.
Firehole lake is a beautiful shade of blue on a sunny day.
Midway Geyser Basin South of Firehole Lake Drive is the Midway Geyser Basin. You won't want to miss deep blue Grand Prismatic Spring surrounded by brilliant shades of green, yellow, orange, and red. This is one of the most outstanding photo subjects in the area. For a great photo, hike up the north end of the parking area to Bluff Point. The next stop is a short side road to the right that takes you to Biscuit Basin.
