Moon hidey hole for our first colony

Holes in the moon may never be colder than 40 degrees below zero at the bottom.  A good sheltered spot for a Moon Base.  Collapsed lava tubes likely have extended underground spaces.
"Could swallow a football field".

Another hole. You can see rubble in the bottom. About 100 yards across

"Good place to start a colony"
