Went up there last night. There is also a Forest Service BM up there on the summit of The Brother. Sure wish I could access their database for BM elevations! Anyone have any ideas there?
John - I think you found one of the 27 stupid geocaches up there when you were up there. Evidently, there also used to be an ammo box geocache on The Brother, but it has recently disappeared. Now, if you ask why there are freakin' 27 geocaches in this park, I have no answer. DUMB.
On a fun note, all of that gneiss that has potholes is FULL of water, and frogs are using it as breeding grounds - frogs on the summit of The Brother! Cool!
