Do you ever run/trek with a GPS? I'm updating map of trails in Shenipsit SF (Soapstone course is getting some re-routes to avoid some private land issues) and surrounding public lands like Whittaker/McCann and note that I don't have any trail data for the forest parcel that runs from your place over to Handel by Pomeroy Reservoir/Dam - I assume that is what you refer to as the dry dam?
Anyway, if you have any tracks or don't mind recording some over the next few weeks, I can include them on the new map version. Or if you lack hardware, maybe you and I can do a tour of the known trail systems in that parcel one of these days..
I can certainly provide you with a GPS track of the trails. Let me make a good version for you.
