The Sierra Club Bulletin, 1908. 1st Edition . Soft cover. Fine. Pp 226-234 + Photographs, Drawings. Brown Card Covers. Fine, Clean, Unworn, Unfaded, Two Small Name Stamps Of A Geological Survey Geologist. Grove Karl Gilbert (1843 -1918), Known By The Abbreviated Name G. K. Gilbert In Academic Literature, Was An American Geologist. He 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 An Important Monograph, The Geology Of The Henry Mountains (1877). After The Creation Of The U.S. Geological Survey In 1879, He Was Appointed To The Position Of Senior Geologist And Worked For The Usgs Until His Death (Including A Term As Acting Director). Gilbert Published A Study Of The Former Ancient Lake Bonneville In 1890 (The Lake Existed During The Pleistocene), Of Which The Great Salt Lake Is A Remnant. He Named That Lake After The Army Captain Benjamin L.E. De Bonneville, Who Had Explored This Region Previously. The Type Of River Delta That Gilbert Described At This Location Has Since Become Known To Geomorphologists As A Gilbert Delta. In 1891, Gilbert Examined The Origins For A Crater In Arizona, Now Known As Meteor Crater But Then Referred To As Coon Butte. For A Number Of Reasons, And Against His Intuition, He Concluded It Was The Result Of A Volcanic Steam Explosion Rather Than An Impact Of A Meteorite. He Joined The Harriman Alaska Expedition In 1899. Two Weeks After The 1906 San Francisco Earthquake, Gilbert Took A Series Of Photographs Documenting The Damage Along The San Andreas Fault From Inverness To Bolinas. Gilbert Is Considered One Of The Giants Of The Sub-Discipline Of Geomorphology, Having Contributed To The Understanding Of Landscape Evolution, Erosion, River Incision And Sedimentation. Gilbert Was A Planetary Science Pioneer, Correctly Identifying Lunar Craters As Caused By Impacts, And Carrying Out Early Impact-Cratering Experiments. He Coined The Term Sculpture For A Pattern Of Radial Ridges Surrounding Mare Imbrium On The Moon, And Correctly Interpreted Them In 1892 As Ejecta From A Giant Impact.? Gilbert Was One Of The More Influential Early American Geologists. He Won The Wollaston Medal From The Geological Society Of London In 1900. He Was Elected As A Member To The American Philosophical Society In 1902. He Was Awarded The Charles P. Daly Medal By The American Geographical Society In 1910. Gilbert Was Well-Esteemed By All American Geologists During His Lifetime, And He Is The Only Geologist To Ever Be Elected Twice As President Of The Geological Society Of America (1892 And 1909). Craters On The Moon And On Mars Are Named In His Honor, As Is Mount Gilbert In Alaska, A Second Mount Gilbert In California, And Gilbert Peak In The Uinta Mountains Of Utah.
