Sunset Crater, Arizona

Snooker - apparently you found the puzzle after all - even with the missing link in the link I posted! Clever lady!

Yeppers. After playing with these, I have a new appreciation for the craters on the moon. Even though I "know" they are craters, I've always thought of them as just kind of rumply color changes. I think I'll go back and look for some of the pics that came out of the moon exploration days... Thanks, PH and snooker!

Snooker has said it well!

Doesn't give any indication of the inside does it? The view from the air is so much better. Thanks, tater. :)
