Grove Karl Gilbert (1843 – 1918) was a major figure in American geology. Gilbert was born in Rochester, New York and graduated from the University of Rochester. In 1871, he joined Wheeler's geographical survey of America west of the 100th meridian as its first geologist. He then joined the Powell Survey of the Rocky Mountain Region in 1874, becoming Powell's primary assistant, and stayed with the survey until 1879.] During this time he published one of his most important monographs, "The Geology of the Henry Mountains". After the creation of the U. S. Geological Survey in 1879, Gilbert was appointed to the position of Senior Geologist and worked for the USGS until his death. Gilbert’s report on the Henry Mountains is a classic field geology study for its contributions to our knowledge of igneous structures known as laccoliths and for its contributions of geomorphic processes. His work pioneered many concepts which are now taken for granted by geologists.
