This report describes the crustal deformation of the Yellowstone Hotspot from 1923 to 1995. Measurements show that the Yellowstone Caldera underwent rapid uplift from 1923 to 1985; this was followed by ten years of subsidence. The report also summarizes the University of Utah's research program to monitor the caldera using GPS stations. Information on surrounding fault zones is also provided.
