Jimmy, it is behind a fence, in a quarry. As you leave Tenino, south bound, follow old 99 under the railroad bridge, and it starts to head east toward the freeway. (not southbound 507) on the left of the road, I'd say less than a mile from the railroad bridge, is the quarry/gravel pit.
Can you tell me where 'kalach beach' is? you feature it on redpointfilm.
