Tis' a shame the Memaloose area isn't well respected. True, the area has been abused by yahoos and chainsaws but the Memaloose Creek area has quite a lot of old growth forest downstream of the trailhead. No trails in the area but it is literal wilderness so it's special down there.
Be warned, the yahoos drive like yahoos down that road, taking turns far faster than safe which has caused a few accidents over the years.
Those shot up quarries along the way have to go, nothing but a magnet for negative behavior. Shot up burned out cars and mounds upon mounds of trash. "If you build it they will come"!
