A good map you can probably get at any Forestry office is "
The Forest Land Use Zones of the BIGHORN BACKCOUNTRY"
Here is a site related to it. (

Camping on just about any level spot on Crown Land is often called "random camping" That is, not in a campground. A lot of people do it and as long as they don't cut down live trees, litter, have unsafe fires or leave fires unattended (a big NO, NO) it is ok. If people drink and have loud music and cause trouble for others trying to enjoy the outdoors, then they will be dealt with by the authorities.
