West Triplet Geyser is a geyser in the Upper Geyser Basin of Yellowstone National Park, Wyoming.[1] West Triplet Geyser is south of Grand Geyser.[2] Its activity is related to that of Grand and Rift geysers. West Triplet erupts to a height of about 10feet, usually during Grand's quiet periods. Before 1947 it displayed regular activity, erupting about every three hours.[3]
