Thomas Wilson Dibblee, Jr. (1911 –2004)

In over 60 years of active mapping, Thomas Wilson Dibblee, Jr., created a true California legacy through his geologic maps and reports. They provide an unsurpassed regional perspective that contributes a wealth of locally important information. His knowledge of regional stratigraphy, structure, and paleontology was foundational to the current understanding of much of California’s geology. The magnitude, integrity, and permanence of Dibblee’s geologic mapping of one fourth of the state of California is unprecedented.
