| Topic | Sediment: Matthews Road Densities All Ten Mile River Sub-Basins |
The map image above is from the KRIS Ten Mile Map project in ArcView and shows road construction from 1942 to 1999. Older roads were mapped by Matthews and Associates (2000) from aerial photos and digitized into ArcView. Newer roads (since 1988) are derived from data provided by the California Department of Forestry. The legend at left shows road construction by period. The KRIS Ten Mile project covers sub-basins adjacent to the Ten Mile River, which were not studied by Matthews and Associates. Thin red lines are USGS 1:24,000 roads from DRGs.
