Tony and I hiked in the nature reserve north of the Upper Peirce Reservoir on Sunday. This is the approximate route taken in our journey. The trail meandered originally and we had followed it.
The actual distance is greater than the 7.62 km recorded on Google Earth. The photos here are from Google Earth. 5076 feet (1.5 km) elevation approximately.
We made very good time in the morning. When the trails disappeared in the afternoon, we had to force our way through the difficult terrain, avoiding ravines and creeks.
Some terrain were close to impossible to traverse but we continued to force our way though.
