What are 'y' and 'D' for forest roads and trails?
In southern California at least, USFSroads are numbered with yDxx, where yD
is the PLSS[0] township in which the north (?) end of the road lies and xx
is a serial number. Trails are numbered xDyy, where xD is the PLSS range in
which the trailhead is found and yy is a serial number.
