According to the county assessor every property you touch is on public/state land. There is a "Private Property" sign on the gate that's on public land entrance to the road. I'm assuming it's a similar situation with the first gate at the Homestead and many other parcels in the area: everyone, close the gate behind you and were good!
Silver Creek near the Homestead? If so I put up half dozen routes + there and think it is a sensitive area and should be kept off Mountain Project :) Sacred land. Develop what you want and enjoy. No need for it here.
