Paper Abstract

In February of 1972, initial discus sions were carried on with Mr. Al Klahn, Assistant Engineer, for Placer County on doing a complete Photolog of all county maintained roads and highways. This consisted of 1000 one way miles, a total of 2000 miles of roads, in a county measuring approximately 80 miles from West to East and 22 miles North to South. Terrain ranged from flat farm land to densley forested mountains to the shores of Lake Tahoe. Road conditions varied from well paved streets to routes that were barely logging trails.
