Lee, If you have not found it allready okanogan trail riders has a website with some usefull information, and according to a local will soon have a GPS map posted on their site. I think there is a dealer in the valley somewhere. The area consists of a couple of drainages with traile everywhere. We spent three days plain hauling a$% all over this spring and again last weekend. What is so awesome about this place is that there seems to be no restrictions about staying on the trails etc. I love technical single track, like we have in the PNW, but it is a blast to be able to ride anywhere you want( cross country). Numerous times this last weekend I would look to one side then the other to watch my riding companions blasting along blazing new trails, toatal riding freedom! A GPS might be nice but we camped at what is called the Upper Pits which sits at the bottom of a large steep meadow that is visible from many of the vistas in the area. Camping in that spot made it easy to keep our bearings. I am hesitant to post this info on larger more widely read sites for fear of the secrect getting out, in fact my riding bros would likely be pissed I posted any of this.
