An expedition to Mars finds life and a series of mysterious holes that line up perfectly.
History
First publication: Galaxy January 1954
Review
This is a pretty good story, but not great. First, the science is impossible. Second, it is too short to really build the world or the aliens of Mars. Character is fairly good for early fifties SF. An enjoyable story to read.
