- 18 letters to Sir Archibald Geikie from Captain Clarence Edward Dutton of the United States Geological Survey (USGS) concerning geological observations in the United States and the organisation of the USGS (1880-1891)
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton enclosing copies of topographical drawings of the Grand Canyon by William Henry Holmes. He pontificates over what text he will eventually send to accompany the drawings and asserts that the Grand Canyon was formed during the Pliocene and the Quaternary geological periods rather than by erosion during the Tertiary period. He promises to forward copies of Holmes' drawings of the Kaibab region shortly. He reports that John W Powell...
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton telling Geikie that he has declined the invitation from the journal Nature to review Geikie's forthcoming publications, as he will shortly be leaving for the Sandwich Islands (now Hawaii) to do field work in preparation for a systematic study of the volcanic fields of California and Oregon. He recommends his colleague Grove Karl Gilbert for the task and asks Geikie if he will review his new monograph...
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton apologising that he has only been able to send final proofs of his atlas sheets for Tertiary History of the Grand Canyon District, ( 1882) at the current time. He apologises for being unable to review Geikie's forthcoing books due to his forthcoming field work in the Sandwich Islands (now Hawaii) and pontificates that Grove Karl Gilbert will do a better job in the long run. He reports that Gilbert and his...
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton giving the background details to the current Congress debate concerning the expansion of the United States Geological Survey to incorporate individual State Surveys. He reports that he will shortly be leaving to undertake field work at the Grand Canyon and requests that Geikie send his sister copies of the review he has written of Dutton's book.
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton, thanking him for his articles on weathering and postulating that the Grand Canyon was formed in this manner, and that he is preparing a section concerning this for Geikie's manual. He recommends William Henry Holmes' topographical drawings of the Grand Canyon and reports that photolithographs are being prepared. He gives details of the depths of the individual geological stratifications which can be observed at the Grand Canyon....
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton. He encloses a report by Clarence King and explains the poor quality of his own entry in this. He discusses the formation of the basaltic plateaux which are cut by the Grand Canyon in the light of some articles written by Geikie. He concludes that there are 2 models of volcanic eruption: The Mediterranean Type where many small eruptions concentrated in a small area produce cinder cones and the Rocky Mountain Type where few very...
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton discussing his field trip to the Sandwich Islands (now Hawaii). He reports on the large scale of the ultra basic basalt lava flows of the Mauna Loa eruption and the lack of cinder cones. He reports on the ferruginous nature of the lavas and their high olivine content along with observed layers of hematite and magnetite. He describes the volcano's impressive topography and its inability to support running water. He asks...
Scope and Contents Letter to Sir Archibald Geikie from Capt Clarence Edward Dutton discussing the fossiliferous Upper Cambrian metamorphosed sandstone shales found at Lake Superior and the Grand Canyon. At Lake Superior these beds overlie 1400 feet of unfossiliferous sandstone and shale, interspersed with layers of copper bearing metamorphosed volcanic ash. These are the same as the Huronian metamorphic beds at Lake Huron which are possibly of the Lower Cambrian age due to an unconformity (as identified by Alfred...
