Creeping Death,
As far as the maps go....
www.topozone.com has good topographic maps
www.mytopo.com has really good customizable maps for sale that you can build on their server and then purchase.
And my all time favorite is google earth for satellite images that you can customize, email jpegs to yourself, then laminate and take in your backpack.
The combination of these is more than enough to give you what you need to get to know, short of first hand experience in that area.
I don't believe there are detailed maps of elk bedding areas and watering holes and such, like you can purchase in AZ or NM, for WA state. To be honest, I prefer it that way, you will too if you find a honey hole.
For maps, these sights should serve you well. The USGS is another good source, but some of the maps they have are really old and outdated, especially for the West side.
Good Luck,
Autumn Pulse
