Near Keogh in Oneida County, Idaho — The American West (Mountains)
Formed in a basin from which no river reached the ocean, this became the largest lake in North America. Finally the lake rose high enough to overflow into the Snake River. Then after the climate got drier, and the great basin of Utah and Nevada became mostly a desert, the lake receded. Salt Lake and two other remnants are all that are left of this old 20,000 square mile lake.
