Discovery of a Balkan fresh-water fauna in the Idaho formation of Snake River Valley, Idaho
In 1866 Gabb described Melania taylori and Lithasia antiqua "from a fresh-water deposit on Snake River, Idaho Territory, on the road from Fort Boise to the Owyhee mining country. Collected by A. Taylor." He states that a small bivalve, perhaps a Sphaerium, was associated with them.
Revision of the Beckwith and Bear River formations of southeastern Idaho
In the detailed geologic mapping of the Wayan and Montpelier quadrangles, in south-eastern Idaho and adjacent territory, it has been found necessary to apply new names to strata hitherto referred to the Beckwith and Bear River formations or to portions of the Laramie as mapped by the Hayden Survey. The two quadrangles are contiguous, and the Montpelier quadrangle lies south of the Wayan. They occupy the corner of the State and include a very narrow strip in northeastern Utah and a somewhat broader strip in western Wyoming.

Profile surveys in Bear River basin, Idaho
Bear River rises on the northern slope of the Uinta Mountains, in the northeastern part of Utah, and after a circuitous course in which it leaves Utah and enters Wyoming, Utah, and Wyoming in turn and makes a long detour in Idaho it returns to Utah and finally discharges its waters into Great Salt Lake. The maximum elevation of the upper rim of the basin is 13,000 feet above sea level. The upper part of the basin comprises a rough, broken country, well drained by numerous short streams, most of which are confined to steep, narrow canyons. The streams are fed by many small springs and by the melting of the snow which forms the greater part of the precipitation. The rocks of the extreme headwater region are chiefly sandstones and quartzites and are covered with a thin layer of soil that supports scattered groves of fir and aspen. A few small lakes lie near the head of the river.
