During the second world war Glen Evans was active in the search for mineral deposits in Texas. Especially those of importance to the war effort. We have included a selection of the minerals that were collected by him during that time. Some of these specimens have formed integral parts of Museum exhibits, and others important sources of data for publications. 

It is not enough to know that a particular mineral exists in an area; the extent and quality of that mineral must be analyzed in order for geologists to assess whether the mineral is an economic deposit. Glen was required to make those recommendations in the reports that he wrote for the Bureau of Economic Geology.
