Diablo Dam, Washington (Google Maps ⧉, OpenStreetMap ⧉)

"…which was the little highway to I7-A that wound into the heart of the mountains and in fact would come to a dead‐end as a dirt road at Diablo Dam. Now I was really in the mountain country."

"I bought forty‐five dollars' worth of groceries on credit in the little Marblemount grocery store and we packed that in the truck, Happy the muleskinner and I, and drove on up the river to Diablo Dam. As we proceeded the Skagit got narrower and more like a torrent, finally it was crashing over rocks and being fed by side‐falls of water from heavy timbered shores, it was getting wilder and craggier all the time."
