1992 Map of Initial Point

USGS Topo · Published 1992

About this map

Initial Point serves as the literal foundation for land surveying in Idaho, marking the intersection of the Boise Meridian and the Base Line north of the Snake River. This 1992 revision reveals a landscape defined by the juxtaposition of high-desert geology and industrial irrigation efforts. Agricultural development is evident through the complex network of the Waldvogel Canal, Southern Lateral, and Summit Lateral, which draw water into the arid plains. Along the river canyon, the Birds Of Prey Natural Area encompasses the dramatic cliffs and basalt formations of Shea Basin. The map captures local land use at the end of the 20th century, from the remote Priest Ranch and various corrals to the industrial presence of Claypits and a Pumping Sta supporting the region's water management systems.
