1971 Map of Philip Smith Mountains A-3

About this map

The Continental Divide dictates the flow of water across this high-latitude terrain, marking the fundamental drainage separation in the Brooks Range. Flowing through the central portion of the quadrangle, Your Creek represents one of the few named watercourses in this isolated landscape. This 1971 survey, based on aerial photography from the previous year, highlights a region characterized by its lack of established infrastructure, noting that no roads or trails existed in the area at the time of publication. The southern edge of the sheet is defined by the South Boundary Umiat Meridian, a critical reference point for the Bureau of Land Management in managing these unsurveyed and unmarked land lines.
