Chinese camp tent frame.
This tent frame is constructed of native juniper. The soil on this hillside is rocky, the hill has little underbrush. The depression under the tent frame is similiar to depressions noted in other Chinese camps; that the tent frame has survived 130+ years is more than likely due to the lack of wildfire on this dry, stony hill, as well as its out-of-the-way location where was not found and disturbed by tourists.
