The Miles Mineral Museum is located in Roosevelt Hall, Room 103, adjacent to the Natural History Museum. Admission is free.

When Fred Miles and his wife Gladys moved to Roswell, New Mexico in 1928, they began exploring along the Pecos River. There they found beautiful quartz crystals called Pecos Valley Diamonds. This was the beginning of a love affair with minerals and rocks that lasted 40 years and marked the beginning of the Miles Collection. The collection was displayed in a back room of Fred's Texaco service station on Second Street in Roswell. If you mentioned any interest in minerals or rocks, Fred would proudly show off his collection, which also included Native American artifacts.
