Videos of Upper Geyser Basin

Infrequent but violent eruptions characterize Giantess Geyser. This fountain-type geyser erupts in several bursts 100 - 200 ft (30 - 60m) high. Eruptions generally occur 2 - 6 times a year. The surrounding area may shake from underground steam explosions just before the initial water and/or steam eruptions. Eruptions may occur twice hourly and continue for 4 - 48 hours.

This video shows a brief tour of the Upper Geyser Basin during a time when the area is only accessible by oversnow travel. Highlights include a steaming Castle Geyser, and eruptions of Grand and Old Faithful Geysers. Other features include Crested Pool, Scalloped Spring and Firehole River.
