Continental drift orogeny at the boundaries of convection cells. By 1967, barely two decades after discovery of the mid-oceanic rifts, and a decade after discovery of the striping, plate tectonics had become axiomatic to modern geophysics. In addition, Marie Tharp, in collaboration with Bruce Heezen, (who initially ridiculed Marie's observations that her maps confirmed continental drift theory), provided essential corroboration, using her skills in cartography and seismographic data, to confirm the theory. Evidence for the movement of continents on tectonic plates is now extensive. Similar plant and animal fossils are found around the shores of different continents, suggesting that they were once
Drift Desert, Arizona Drift Desert, Arizona Drift Desert is a former ranch and steamboat landing on the Colorado River, now a ghost town, in La Paz County, Arizona. Drift Desert was a ranch with a woodyard landing for the George Alonzo Johnson's steamboats on the Colorado River. It was located 102 miles up river from Yuma, Arizona, 30 miles above California Camp and 29 miles below La Paz, in what was then Yuma County, Arizona. Drift Desert appears on the 1861 Geological Map No. 1. Prepared by J.S. Newberry, M.D. Geologist to the Expedition. Explorations and Surveys. War Department. Map No. 1. Rio
