Lost black Bose QuietComfort 35 headphones with a small scratch on the right ear cup near Deep Creek Lake, Western Maryland.

I lost my black Bose QuietComfort 35 headphones while camping at Deep Creek Lake in Western Maryland. I last remember having them out while setting up my tent, but I can't find them anywhere. They have a small scratch on the right ear cup, and the battery was fully charged. These headphones are very important to me, so any help would be greatly appreciated!
