1957 Map of Initial Point

USGS Topo · Published 1985

About this map

Initial Point stands as the fundamental geographic marker for Idaho's cadastral surveys, situated at the intersection of the Boise Base Line and the Boise Meridian. This 1957 record, updated with 1970s aerial data, captures the arid landscape where the plateau drops sharply into the Snake River canyon. The presence of the Waldvogel Canal and the Southern Lateral illustrate the complex irrigation infrastructure required to sustain agriculture in this high desert environment.
