This route was not produced from a recorded track but was originally mapped northbound using Gaia GPS by Dan Scotina.
I reversed the track for a southbound hike and imported it into CalTopo for easy sharing. I also added pertinent information such as mileage, campgrounds, stores, and other details to create a rudimentary guide of sorts.
Additionally vs the OSM layer -
* Show the more scenic Borders Farm reroute that gets off the road
* Added Kenyon Hill reroute that avoids private property issues
