Road Trip pic of the day, 7/23: Where is this?

Road Trip 2009 has taken me past more waterfalls than I can count, and that's certainly a good thing. But this one stuck in my memory. Be the first to tell me where it is, and you'll win a prize.

When I saw this waterfall, during one of my Road Trip 2009 stops, I was really taken by it. And that's why it's today's Road Trip picture of the day challenge: Be the first to tell me where this is located, and youll win a prize. Daniel Terdiman/CNET

Update (Friday, 3:19 p.m.): The answer is Idaho Falls, Idaho.

SIERRA MADRE MOUNTAINS, Wyo.--Drive more than 5,000 miles in a month, as I have on Road Trip 2009, and you'll go by all kinds of amazing natural attractions. For me, many of my favorites have been the many, many waterfalls I've gone by along the way.

But for some reason, this one has stayed with me. And so I wondered if it has stayed with other people who have seen it. And that led me to make it today's Road Trip picture of the day challenge.

If you're the first person to e-mail me (at daniel--dot--terdiman--at--cnet--dot--com) with the location of this particular waterfall, I'll have a prize for you. Please be sure to include "Picture of the day, 7/23" in your e-mail subject line.

Good luck.

For the next few days, Geek Gestalt will be on Road Trip 2009. After driving more than 12,000 miles in the Pacific Northwest, the Southwest and the Southeast over the last three years, I'll be writing about and photographing the best in technology, science, military, nature, aviation and more in Wyoming and Colorado. If you have a suggestion for someplace to visit, drop me a line. And in the meantime, join the Road Trip 2009 Facebook page and follow my Twitter feed.
