A Moon Pic Site

People,

There are some interesting Moon pics on this page, and some astro-nut conversation.

There is a pic of a tall, spindly tower that I have never seen before. And about halfway down there is a pic showing a large, cavernous opening that you could fit an aircraft carrier through.

There isn't much reading, mostly pics. It's a quickie.

It seems familiar, maybe we have seen it before.

Cheers!
