Haven't hunted those particular units, but if you can cover enough places at least a rough/steep/blowdown-covered mile from the trails, where horses can't access, at least 1,000 vertical feet up or down, you'll find elk, guaranteed. Stay mobile and stay after them until you find them. Don't walk too many trail miles--you lose your competitive advantage over horse folks. This kind of great elk hunting is simple and predicable to find, pretty hard to get to, and darn near impossible to bring meat out! Which is why most folks don't do it.
