Horizontal rock glacier displacements were measured by tracking large surficial rocks on temporal orthophotos from 1978, 1990, and 1999. Vertical change was measured by creating digital elevation models (DEMs) from digital stereopairs
, then substracting elevations to detect change. Because horizontal and vertical change is minimal, Front Range rock glaciers appear to be adjusted with current climate.
