Hunted GMU25 3 or 4 years ago. I don't have any pictures that would be useful for you but here are my 'field notes'.
1. Hunting ground is roughly 50/50 alpine meadow and dark timber stands. The elk (and deer) we saw were solely in the timber, although paths were apparent through meadows for migration to and from water.
2. As others mentioned above, access is steep with a lot of fallen timber to navigate. Good ankle support boots and walk in and out with your buddies. Seriously, some of those climbs can put you in a world of hurt if you slip.
3. I'd recommend scouting not just your hunting area but the roads in and around there. Some of them are pretty rough and get worse with weather. Coffee Pot road comes to mind.
4. The area we were in was part of a BLM cattle lease. Not a big problem, but tracking was problematic with all the hoof-churn in some areas.
5. Because of the terrain you'll probably see several drainages in the area you settle in to. There are even small wetlands here and there, maybe 50 feet across or smaller. Critters love that stuff if it's not frozen over.
6. Don't be afraid to 'get higher' if you're not seeing the Wapiti., especially if it's still warm. Deer are more tolerant of the heat.
7. We saw a half dozen fat and sassy does 10 minutes into our first day. If you put in only for elk, consider also buying an OTC deer tag. GMU25 usually has some left over tags available.
Good luck and have fun!
