I hunt manastash every year. The elk don't leave the area. They go deep and dark. Look at a map of the deepest and darkest holes with no trails and I'd almost guarantee there to be elk near by. 90% of the hunters in that unit only hunt for maybe 3-4 hours then head back to their camp. Pack a lunch, cover ground and you'll find lots of animals. I've had a hard time finding cows lately I'm there. Lots of single bulls though.
