description Clarence Dutton Overview

Clarence Dutton was an American geologist and United States Army officer whose work for the geographical and geological surveys of the American West included studies of the Colorado Plateau, Grand Canyon, and volcanic regions. He introduced the term isostasy in 1889 for the gravitational equilibrium by which the Earth's crust rests at different elevations according to its thickness and density. His reports were also noted for vivid descriptions of western landscapes.

help Clarence Dutton FAQ

What geological concept did Clarence Dutton coin?

Clarence Dutton coined the term 'isostasy' in 1889 to describe the gravitational equilibrium between Earth's crust and the denser mantle beneath it. The concept explains how elevated mountain ranges have deep crustal roots, analogous to icebergs floating in water, maintaining balance across the lithosphere.

Did Clarence Dutton study the Grand Canyon?

Yes, Dutton conducted extensive geological surveys of the Grand Canyon region while working for the U.S. Geological Survey in the 1880s. His 1882 monograph, the 'Tertiary History of the Grand Cañon District,' is considered one of the most important geological publications of the 19th century and featured illustrations by artists Thomas Moran and William Henry Holmes.

What did Clarence Dutton contribute to the study of volcanoes?

Dutton made significant contributions to volcanology through his detailed field studies of Hawaiian volcanoes and other volcanic regions. He proposed a classification system for volcanic eruptions based on the nature and intensity of explosive force, helping to systematize the young science of volcanology in the late 1800s.

What was Clarence Dutton's role in the U.S. Geological Survey?

Dutton served as a geologist with the U.S. Geological Survey, where he conducted fieldwork across the American West during the late 19th century. His colleagues included John Wesley Powell, and together they were part of a generation of government scientists who systematically mapped and interpreted the geology of the western territories.
