Getting There

Navigate to 44.485050, -110.852547.

Route

Biscuit Basin is part of Upper Geyser Basin.

The following information was taken from the Old Faithful Area Trail Guide, which is available at the Old Faithful visitor center.

Three miles (5 km) north of Old Faithful is Biscuit Basin, named for the unusual biscuit-like deposits that used to surround Sapphire Pool. Following the 1959 Hebgen Lake Earthquake, Sapphire erupted, and the "biscuits" were blown away; it last erupted in 1991. Sapphire remains one of the most beautiful blue pools in the park. Mustard Spring provides a bright color contrast, and Jewel Geyser adds excitement as it erupts every 7-10 minutes.

We went to Yellowstone as a family. We drove the loop and stopped at most of the overlooks and short hikes.
