Road Trip pic of the day, 7/9: What is it?

This military hardware was a staple of Cold War thinking. Do you know what it is and where this particular example of it is located today?

Update at 9:22 a.m. PDT: We have a winner. It's a BOMARC B--Boeing/Marc CIM-10B surface-to-air missile housed at the Hill Air Force Museum, near Ogden, Utah.

BOISE, Idaho--Out here on the highways of Colorado, Utah, and Idaho, I've seen a lot. I'm on Road Trip 2009 and making daily stops at military installations, national parks, small towns, big cities, energy research institutions, and more.

That means I take a lot of pictures, and every day from here until the end of Road Trip 2009, I'll be presenting you with one picture--and a challenge.

On Wednesday, I challenged you to identify the large yellow sphere, in the picture below, that's located in Arco, Idaho. In part it was because I wanted to know what my readers would think it was and, I'll be honest, it was also because I didn't know myself, and I wanted to. I got lots of responses. But, my dear readers, none of them seemed like the correct answer. So the prize for being the first to send me the right answer is still available.

Now, however, I'm offering up a picture that I do know the truth about. So in this case, I want to hear from you about what it is and where.

I'll give you a hint: it's a Cold War-era relic, clearly military, and currently located in Utah.

If you're the first person to send me the right answer, Thursday's prize is yours.

Please send your thoughts to daniel--dot--terdiman--at--cnet--dot--com, and include "Pic of the day" in the subject line. If you're the one, I'll get back to you.

Good luck.
