Miscellaneous geysers and other thermal features in Yellowstone. These include the Upper Geyser Basin (Old Faithful, Morning Glory Pool, Daisy, Riverside, Castle and Grotto Geysers), the Norris Geyser Basin (Steamboat Geyser - the worlds largest geyser), West Thumb Geyser Basin, Biscuit Geyser Basin, Mammoth Hot Springs Terraces and Geysers, Lower and Midway Geyser Basins and the Mud Volcano area.
Note: During our trip, Steamboat Geyser errupted at 10pm Friday Sept 13th 2002. This is a very rare occurance and we got to see Steamboat Geyser Saturday morning while it was in it's "steam" phase which lasts approximately 24 hours after an eruption.
