The Journal of Mammalogy in Vol. 11, No. 3 (Aug., 1930), pp 300-303 included this introduction describing the work done in Idaho:
A NEW PLIOCENE HORSE FROM IDAHO
BY JAMES W. GIDLEY

Late in the summer of 1928, the U. S. National Museum received a few small lots of fossil bones from the Snake River Valley, Idaho, collected by Dr. Harold T. Stearns in connection with his work on ground-water resources. These and the reports sent in by Doctor Stearns gave such promise of a profitable collecting field that the Smithsonian Institution sent an expedition there the following summer (1929). This expedition obtained additional collections of considerable interest and value. By far the most important lot collected consisted of a quantity of well preserved fossil remains of an extinct species of horse belonging to the rare genus Plesippus. These specimens came from a fossil bone deposit in the vicinity of Hagerman, Idaho. The credit of discovery of this deposit goes to Mr. Elmer Cook, a resident of Hagerman, Idaho, who reported it to Dr. Stearns. The Smithsonian party collected here a quantity of well preserved material all pertaining apparently to a single species of horse. This material includes several skulls and jaws and numerous bones of all parts of the skeleton, representing ages ranging from young colts to old adults of both sexes.
