Digital Geology of Idaho
We are constructing a web-based Digital Geology of Idaho that consists of a newly compiled digital geologic map of the state, with ten to fifteen topical units on the geology and geography of Idaho. The topical units, keyed to the map, will contain photographs of Idaho's diverse rocks and landscapes, plus three- and four-dimensional Virtual Reality cross sections and visualizations (with geologic time as the fourth dimension).
	In this image Landsat band 3-2-1 are drapped over dem and show important elements which include the late Cretaceous Atlanta lobe of the Idaho batholith, Miocene sandstones and volcanic rocks formed on the shoulder of the western Snake River Plain, the Neogene to Pleistocene sedimentary and volcanic infilling of the western Snake River plain as it subsided along the Boise Front fault and other structures, Holocene basalt cinder cones, and the 14,500 year Lake Bonneville Flood that produced both scoured lava surfaces and slackwater deposits that underlie rich farmland.
