452 r. arnold reconnaissance of the olympic peninsula 



Introduction 



During the months of June and July, 1904, the writer, under the 

 direction of Dr William H. Dall, made a reconnaissance of the coast of 

 the Olympic peninsula, Washington, from Port Angeles, on the south 

 shore of the strait of Juan de Fuca, to Grays harbor, on the Pacific. 

 Chester W. Washburne, of Eugene, Oregon, and Eussell G. Wayland, of 

 Seattle, assisted in the work. The trip was primarily undertaken for the 

 purpose of collecting the fossils and working out the stratigraphy of the 

 Tertiary rocks of the region; in addition to this, however, notes were 

 made on the other important geologic features of the country traversed. 

 This paper embodies an outline of the results of the reconnaissance. 



Mr J. S. Diller, of the IT. S. Geological Survey, visited the region of 

 Clallam bay in 1892 to investigate the coal deposits there, and Professor 

 Henry Landes and a party consisting of Messrs Charles Landes, Charles 

 A. Euddy, and S. H. Eichardson, made a hurried reconnaissance trip in 

 1902 over practically the same route as that taken by the writer, but 

 neither Diller nor Landes published any notes on the region. It was 

 through information furnished by Professor Landes that Doctor Dall was 

 induced to send the writer into the country in 1904. 



Previous Litekature 



Probably no other territory of equal extent in the United States has 

 received as little attention from the explorer or geologist as has the Olym- 

 pic peninsula, and as a result the literature directly concerned with its 

 geology and natural aspects is confined, so far as the writer is aware, to 

 four papers. 



Mr S. C. Gilman,* a civil engineer who visited a considerable portion 

 of the region in 1895, has given us a fairly accurate map and a good gen- 

 eral description of the peninsula, especially the central mountainous parts. 



Dodwell and Eixon,f the forestry experts who examined the Olympic 

 forest reserve, give some notes of interest to the geologist in addition to 

 their technical report on the forest conditions. 



Some observations on the geology of the southwestern coast of the 

 peninsula are also included by Mr H. S. Conard in an article on "The 

 Olympic peninsula, Washington." X
