The track at this location is following a firebreak, all be it one that hasn't been maintained in many many years

This is a common mode of Cross Country or XC travel here locally as trying to penetrate the dense chaparral is a painful and frustration experience for most.

Most of the currently maintained firebreaks are done with firefighting bulldozers caterpillar model D8 or similar heavy equipment
