Abstract:
Major and Minor Ridgelines for Napa County

Purpose:
Provides qualitative identification of prominent ridges selected from sub-watershed division lines

Supplemental information:
Sub watershed boundary source files:  <east_wtshd> and <west_wtshd>;  then used a qualitative approach of selecting segments of prominent ridgelines based on relative surrounding elevations and amount of scenic highway viewshed exposure.
