Flagstone is an amazing andesite crag located off Forest Road 350 in the Willamette National Forest. Park at a pullout and take a very short hike past an information sign to the crag. There is a wide range of mostly sport climbs with vertical faces and overhangs. The Great White Wall is the first section of the crag that you’ll come to as you approach from the trail. You’ll notice a slab ramp and a roof near the top.
