This is perhaps the most interesting section of emigrant trails along the entire California trail network. From east to west in a distance of about 150 miles almost a thousand miles of trails were created in an effort to find the route with the best grass, most water, least elevation gain, and shortest distance. Below is a webapp of geospatial graphics depicting least-cost corridors (the green blob features), least-cost paths (the red lines), least cost route along the existing trails (purple lines), known emigrant trails (the orange lines). Note that the least cost paths are theoretical -- they are computer generated and may or may not correspond with a trail on the ground. |

Please interact with the map! Zoom in, change the basemap to aerial images, click on a camera to see a picture, click on a thumbtack to see a trail profile. Click on a trail to see its length and elevation data. Enjoy!
