"Found that you can register yourself at the Gerlach P.O. for general delivery and then mail stuff to yourself there."

If you just want you stuff waiting on you until you get there, this may be the answer.

General info from the U.S.P.S. regarding the setup and use of P.O. Boxes.

Application Form 1093 to apply for a box....so you can fill it out in advance:

The use of drop boxes for Appalachian Trail hikers is well documented but here's a website that explains it better than I can.

(This might work as well as getting a full blown P.O. Box for BM but like anything else if abused or if the postmaster gets swamped, it could come to an end.). Anyway based on this it looks like using the U.S.P.S. in one way or another is definitely an option.
