Origin Notes and History of Red Rock Junction

References to Red Rock Junction that document the origin of its place name

REDROCK PASS, Bannock County.—This place is named for the red limestone cliffs which appear on both sides of the pass and was the old outlet of Lake Bonneville. During the Tertiary period, from five to ten million years ago, a fresh water lake existed in the Great Salt Lake basin, which was eleven times larger than the present lake and comparable in size and depth to Lake Michigan. Its water surface was 1,000 feet above the present level, making a great water expanse, the outlet to which was thru this pass down the Portneuf to Snake River (q.v.) and into Payette Lake (q.v.) A time came when the evaporation from this fresh water lake was greater than the precipitation and supply of moisture after which event it dwindled to its present condition and is still decreasing, resulting in a strongly saline aqueous contents. As Captain Bonneville's party was the first to explore this basin to any extent geologists named the geologic fresh water lake for this explorer. Another pass of this name is in northeastern Idaho, which receives its appellation from the Redrock lakes of Montana.—GUIDEBOOK, Overland Route.
