Has Anyone Seen This Waterfall?

TYWKIWDBI found this waterfall picture at Pixdaus, without any location. It looks very much like Pacific Northwest to me in terms of the rocks (resolution is too poor to be very confident, but it looks like multiple thin basalt flows) and in terms of the trees (which look a lot like Douglas-firs). However, despite looking at a hundred or more pictures in various archives, I'm not finding anything that looks like a probable match. My first impression was Salt Creek Falls, but it doesn't have as prominent an overhang. I'm certain it's not in the Columbia Gorge or at Silver Creek Falls (landscape is wrong). This is clearly a large waterfall, but it's not familiar to me. Anyone else recognize this? It may not be in the PNW, it just looks to me like it might be.

Followup, Sunday, 01/03/10: There have been two suggestions so far. First, Snoqualmie Falls, near Snoqualmie, Washington. I had to do a double take on this one; it was one I had looked at fairly carefully before I put this post together. In the fourth comment, I discuss why I cautiously reject this as the same waterfall as the one above. (picture from Google Images)
I have also received a couple of emails from a person at www.iafi.org, who seems confident it's Salt Creek Falls. (Also chosen to capture approximately the same aspect from Google Images) First, the edge of Salt Creek Falls is vertical for a distance, then juts out a bit, causing a step about a third of the way down. The unknown falls above the drop is vertical for a distance, then it recedes into the overhang. Second, the capstone of Salt Creek Falls is one thick intracanyon basalt flow- I've stopped at it a number of times on field trips. The unknown falls appears to be over multiple thin lava flows (though as noted before, the picture isn't high enough in resolution to be very certain of that). Below is another shot, from the e-mailer, with about the same aspect as above, but slightly lower flow. So as of now, I'm still calling this mystery unsolved.
