The maps on this page were created by Jonathan R. Hendricks for the Earth@Home project. Unless otherwise indicated, geologic maps were created using QGIS and USGS data from Fenneman and Johnson (1946) and Horton et al. (2017) using the maximum age values for each mapped unit. Unless otherwise indicated, the 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); greens indicate lower elevation, browns higher elevation; points of highest elevation are marked, as are major cities and physiographic regions.
