Sorry..just being a smart ass. I looked through a google image search, but didn't find that particular image. Is the original file name "full moon mountain" or did you name it that?
The image is from Windows XP desktop backgrounds. It looks alot like mount Rainier in Washington state.
Comparing it to other pictures of Mt. Rainier...I think you're right...it has pretty much the same shape. Spoiler Please Register or Log in to view the hidden image!
Yes, it's Mount Rainier. Here is a picture of it from pretty much the same angle: Please Register or Log in to view the hidden image! And your desktop image for comparison: Please Register or Log in to view the hidden image! See the two ridges in the middle, and the slope with the 'bite' out of it on the left?
