So I hope this doesn't come off the wrong way and maybe I'm barking up the wrong tree, but last September I did a solo trip into a wilderness and came across an outfitter camp about 4 miles into the wilderness. Wall tent, cots, stoves, solar panels, archery targets, a whole setup with the outfitters named stamped on the tent with contact info. This camp looked kept up and the horse trail I took to get into the general area which later led to this had dead fall and logs cut somewhat recent so I don't believe it was left especially with the amount of gear that was up there. Now I've read through some regulations in the past about how outfitters are supposed to be registered apparently and make known what units they work in. Maybe I misread or doesn't apply to wilderness areas? So bored farting around at work i decided to get onto the Colorado Outfitters Association and was cross referencing units I've scouted to know possibly who I may run into/need for a pack out and who and how many outfitters are in the units.
I do not believe that registering with the COA is required with a state licensed outfitter. Its an "association". There are other states where there are many licensed outfitters that are NOT part of an association. Wyoming, Idaho to name a few.
