"Arsenic Concentration in Glacial Till"

This image represents a digital elevation model created with Shuttle Radar Topography Mission (SRTM) data, overlain with a map of glacial till geochemistry (arsenic concentrations in this case). Maps of this type provide a useful tool for assessing the degree of topographic control on geochemical dispersal.
