Seems like the two-pronged peak should be pretty identifiable but I haven't been able to spot it yet. I'm pretty confident it's in WA and probably NW cascades.

Pretty sure Little Devil is in the background. Here's the reverse view per wikipedia: https://en.wikipedia.org/wiki/Little_Devil_Peak#/media/File:Little_Devil_Peak.jpg

Not sure which two-pronged peak you're asking about. Big Bosom Buttes are in the foreground, Slesse is far left, Labour Day Horn and Station D forms a double summit, then the Rexford Group. Pocket Peak partly visible over the col left of North Big Bosom Butte. Looks like the picture was taken from near Twin Lakes.

Thanks. Looks like you're right. It must have been just a little south of Skagway Pass.
