Idaho
Geologic map of Idaho with physiographic regions identified.
Geologic and topographic map of Idaho. Geologic data from Horton et al. (2017) using the maximum age values for each mapped unit. Topographic data are derived from the Shuttle Radar Topography Mission (SRTM GL3) Global 90m (SRTM_GL3) (Farr, T. G., and M. Kobrick, 2000, Shuttle Radar Topography Mission produces a wealth of data. Eos Trans. AGU, 81:583-583).
