I don’t know much about Mountain goats, but I have seen them regularly the last couple of years in the southern part of that unit around Whiterock Mountain and Teocalli Mt.
That tag comes with some strings attached. The Maroon Bells require a permit to camp and the permits are limited so you better secure a permit now for the dates you plan on hunting. As far as scouting goes you will need to acquire a permit for that as well.
