1957 Map of Initial Point

USGS Topo · Published 1972

About this map

Initial Point serves as the geographic anchor for this landscape, marking the intersection of the Boise Base Line and the Boise Meridian from which all property surveys in Idaho originate. The terrain transitions from the high volcanic plateau down to the deeply carved canyon of the Snake River. This 1957 survey (with 1971 revisions) illustrates the extensive irrigation infrastructure essential to the region's development, including the Waldvogel Canal, Summit Lat, and Southern Lateral. Evidence of early settlement and river-based activity appears along the canyon floor at Priest Ranch and the nearby Ferry. The presence of a Flume and Gaging Sta further highlights the managed nature of the water resources. Near the volcanic butte of Guffey, the landscape is marked by Halverson Lake and numerous ephemeral springs, contrasting the arid uplands with the lush river corridor.
