This collection contains one piece of typed correspondence and one hand-drawn and colored map by Robert T. Hill, illustrating Coronado's route through Texas and Oklahoma, both dated 1930.

Robert Thomas Hill (1858-1941) was a significant figure in the development of American geology during the late nineteenth century and in the early part of the twentieth century. As a pioneer Texas geologist, Hill discovered and named the Comanche Series of the Lower Cretaceous, and was a lifelong student of the structure and stratigraphy of the Cretaceous deposits of Central Texas and neighboring regions.
