The question is, what road? They said in the media it was a pullout on highway 37, but you look at photos of the road, it's more like a side road, since there's no center line dividing the directions, like you would find on a highway. Unfortunately, Googlemaps doesn't offer street view of Highway 37, or even a good overhead view of the area. I looked on youtube for possible driving videos past the Stickine , but no luck.
Edit. Okay I found a video of the valley, and it looks like this particular highway doesn't have a center line drawn on it, which to me is unusual. So the images of Leonard Dyck's body were probably taken on Highway 7.
