Special Files for Route 3

Note by Larry Pond, early 2022:
The motivation for developing Route 3 is the current Forest Service closure of some Deep Creek area. The particular closure area prevents access to Deer Mtn via Route 1. The topo PDFs below show the closure area as a green area bounding around Deep Creek. The Deer Mtn Route 1 (DM1) the red route, crosses through the closure area. A violation. The proposed Deer Mtn Route 3 avoid the violation by going around.

With the goal of ascending Deer Mtn as part of collecting Emblems, I found another way. I’m calling it Route 3. We did a private hike of this route on Saturday Nov 13. We had a successful ascent. In our group, We had 3 “I” rated leaders—Bill Simpson, Sharon Moore, myself—and 3 “O” rated leaders—Shana Rapoport, Terri Straub, Teresa Smith---and 9 Participants.

I am pleased with the route. There are steeper portions which can be handled. There are shrubs, none were impenetrable. A variety of hiking capabilities can successfully ascend Deer Mtn using Route 3.

I think that this route will be beneficial during the closure period and beyond. Having a third route fits right in with the Explorer Emblem Awards.
