I guess this is a spider burrow: a conical silk-lined structure incorporating forest debris. Seen in a forest of Douglas Fir and Coast Redwood.

Similar structures with the Foldingdoor Spider Anthrodiaetus riversi have been posted from Pepperwood.
Richard showed us a whole bunch of these structures.
