Stensgar Mt. is North West of Spokane, about 45 miles. This is a new area for most groups. the Author's been going there since the beginning of the sport in 1984, mainly to work on radio equipment, which turned into a winter sport. The green dot indicates the general area. There's a mix of trials and some play areas, including a wide South face. The logging does clean out some areas and possibly opens more areas to play in. The best part is there's NO regulations for permits, etc. So if you wanna test out your new sled and don't have the license-no problem. You drive past Waitts Lake about 3 miles onto the Red Marble road. At this point you can unload or drive up as far as possible. The parking is narrow or along the road and you are on your own for vehicle security (as if that was a surprise). Also note that there's some "hillbilly" type of plant growing, if you take that hint. It's the (suspected) kind that those Fed's fly over during the summer. In the summer, if you stay on the main dirt roads, you should be okay. If you'er a local you'll know where to stay. In the winter it's pretty much untouched, except for other riders, like yourself, so there's not much to be concerned about.
Here's a closer look at the nearby town, of Valley, WA, and Waitts Lake, which is a summer (small) resort as well.
