Preliminary results of precise leveling and trilateration surveys in Yellowstone National Park, Wyoming, 1985
Dzurisin DD, Yamashita KM, Johnson DJ. 1986. Preliminary results of precise leveling and trilateration surveys in Yellowstone National Park, Wyoming, 1985. U.S. Geological Survey (USGS) Open-File Report. 86-265-B. Vancouver, WA
Precise level and trilateration surveys in the eastern part of Yellowstone caldera detected no significant crustal deformation from September 1984 to September 1985. Earlier level surveys had shown that the caldera floor rose by 16-23 mm/yr during 1923-1976, 1976-1983, and 1983-1984. It thus appears that historical uplift at Yellowstone has been relatively steady over time scales of decades, but episodic over time scales of years.
