About this map

Pueblo Valley and the Alvord Valley converge in this high-desert landscape of southeastern Oregon, where water management defines the region's geography. The terminal Tumtum Lake sits at the southern reach of the sheet, fed by the winding course of Pueblo Slough and surrounded by seasonal wetlands. The topography is dominated by the looming presence of the White Horse Mountains to the northeast and the distinctive profile of Snake Den Butte in the west.

A sparse network of unpaved roads, including Whitehorse Ranch Rd and Fields Dr, connects the remote ranching country. The hydrological patterns show numerous small watercourses like Trout Cr, Arizona Cr, and Spring Cr that drain the high ground toward the valley floors. These intermittent streams and marshy pockets indicate a landscape shaped by seasonal runoff and basin drainage common to the Oregon interior.
