This is the downhill singletrack back to FR 6020
. The downhill starts with a moderately rooty decline before you hit a small valley. At the time of riding this there was still tree debris and 3-4 trees had to be hiked over in the middle section. The trail then takes a fairly steep descent through the forest before crossing a bridge and returning to FR 6020
. Take a left here and you'll be back at FR 600 (Oak Creek).
Be careful - this forest is full of poison oak.
