![]() The University airstrip is visible on the east bench east of Red Hill and the University of Idaho, Southern Branch (i.e., the "Twig"). The subdivision of West Pocatello was recently laid out. Newly planted trees can be seen in the right foreground. Three Pocatello city water reservoirs are the only developments on the West Bench, between City Creek and Cusick Creek. On the West Bench, in the lower right are some of the miles of contour ditches dug in the 1930's by the Civilian Conservation Corps. The meandering Portneuf River winds through downtown, unencumbered by a concrete channel. The photograph shows clearly the truncated East and West Benches, which were cleaned off by the Lake Bonneville Flood 14,500 years ago. They had existed at least by 600,000 years ago when the Basalt of Portneuf Valley flowed down the course of the ancestral Bear River. In the distance is Portneuf Narrows cut in the Bannock Range, and beyond that Marsh Valley and the Portneuf Range, with peaks Mount Bonneville and Haystack Mountain.
