Crunchy,
Most of the elk are up high in the park, and other hidy holes. I live in Enumclaw, and used to hunt the White River drainage.
The Tribes hit it pretty hard in August. Add that to a high cougar population, and it makes a pretty tough hunt. Don't get me wrong, there are elk, just not near as many 15 years ago.
Get as far as you can behind locked gates. The Lost lake area is a good place to hike in and possibly spike camp. Good luck!
