There are a few threads going on the MF Elk Zones. Each one is as depressing as the other! As Hamilton alluded to, you are headed to the big time. I haven't spent a whole lot of time in 27 but have a fair amount of time in 26 and 20A. Depending on what time in October you will be in there, that will dictate some of the precautions you need to take. Weather is a big one. All of the roads in these units have substantial summits in them. Be prepared for snow with your vehicle. Google Earth is a fabulous tool, but it doesn't do the steepness or downfall justice.
Where there isn't a spring or creek, it's extremely dry. Have a plan for drinking water. If you spot elk, make a plan and get in there. The elk do not hang in the same area long, and when the decide to bug out, the country they cover can take you at least a day to catch up (that's if they stop). If there are wolves in there, there are elk close. After all they are in the business of eating. If there wasn't anything to eat, they wouldn't be there. That also goes vice versa. If there are elk there, wolves are probably close. Take your time and enjoy yourself! The Frank Church has kicked my ass since I was a youngster and I go back in there every few years. Usually just for muleys though.
