An image of Earth...

from space showing the expansive Snake River Plain (click to enlarge). Where to begin to highlight the various physiographic and geologic features shown on this satellite image?

The Snake River scribes a meandering course as it flows westward across the volcanic plains, with irrigated farmlands adjacent to the mostly incised channel. That's Yellowstone National Park near the upper right, with the Great Salt Lake - and associated salt flats - in the lower center. The geologic structures associated with the Basin and Range Province are easily seen both north and south of the Snake River Plain.
