The Buffalo Ranch
"The Lamar Buffalo Ranch was built in the early part of the century in an effort to increase the herd size of the few remaining bison in Yellowstone, preventing the feared extinction of the species. Buffalo ranching operations continued at Lamar until the 1950s. The valley was irrigated for hay pastures, and corrals and fencing were scattered throughout the area. Remnants of irrigation ditches, fencing, and water troughs can still be found. Four remaining buildings from the original ranch compound are contained within the Lamar Buffalo Ranch Historic District (two residences, the bunkhouse, and the barn) and are on the National Register of Historic Places."
