Abstract

The Snake River Plain is a broad, arcuate region of low relief that extends more than 300 mi across southern Idaho. The Snake River enters the plain near Idaho Falls and flows westward along the southern margin of the eastern Snake River Plain (fig 1), a position mainly determined by the basaltic lava flows that erupted near the axis of the plain. The highly productive Snake River Plain aquifer (water table) is typically less than 500 ft below the land surface, but us deeper than 1,000 ft in a few areas. The Snake River has excavated a canyon into the nearly flat lying basaltic and sedimentary rocks of the  eastern Snake River Plain between Milner Dam and King Hill (fig. 2), a distance of almost 90 mi. For much of its length the canyon intersects the Snake River Plain aquifer, which discharges form the northern canyon wall as springs of variable size, spacing and altitude. Geologic controls on wprings are of importance because nearly 60 percent of the aquifer's discharge occurs as spring flow along this reach of the canyon. This report is one of the several that describes the geologic occurrence of the springs along the northern wall of the Snake River canyone from Milner Dam to King Hill.
