Glen Evans made a substantial contribution to our knowledge of Texas geology. His field work helped to clarify the extent and value of the mineral deposits in this state. 

His excavation of the Odessa meteor crater produced one of the best documented meteor crater sites in the country. 

When NASA was concerned about the astronauts sinking into dust when they landed on the moon, Glen Evans was called to advise them on the effects of such impacts. 

We show you some highlights of his work in geology.
