A large boulder on the roadside. Decent rock, some loose bits. Good shade in summer.
Drive up Upper Sumas Mtn. RD. Follow till the road turns to grave. Down the hill to the corner. The boulder is right beside the road. Park off the road. Gravel Trucks come down to a quarry lower down. Park accordingly.
