In the journals of Lewis and Clark, this name is spelled Kilamox and Killamuck. Gass' journal gives it Callemeux and Cal-a-mex; the journals of Henry and Thompson, by Coues, give it Callemex. For references to various spellings used by early writers, see OHQ, volume
XXVIII, page 183. Tillamook County was created by the territorial legislature December 15, 1853, and has a land area of 1115 square miles according to the Bureau of the Census. For further information about its name and establishment, see Holman's "Oregon Counties," OHQ, volume XI, pages 1-81. Apparently the initial K was changed to a T about the time the county was created. In addition to the county, the name is used for Tillamook (city), Tillamook Bay, Tillamook Head and Tillamook River. Dean Collins' book Cheese Cheddar, Portland, 1933, contains information about the early history of Tillamook County and a popular account of the Tillamook cheese industry, a business of great importance.
TILLAMOOK HEAD, Clatsop County. For the origin of the name Tillamook, see under TillAMOOK COUNTY. The first white man of record to visit Tillamook Head was William Clark, who spent the night of January 7-8, 1806, near the top of the head, and in his journals comments on the fine view to be had, which gave the place the name of Clarks Point of View. Clark was on his way to what is now called Cannon Beach on a short exploring expedition. The wording of his diary has caused several authorities, notably Greenhow and Thwaites, to confuse Tillamook Head with other features further south along the coast. Clark crossed over but one head though his journal seems to indicate two. For additional information see under Capes, Can NON BEACH, ECOLA and Elk Creek. Tillamook Head triangulation station, on the highest point, has an elevation of 1136 feet. Steel says the Clatsop Indian name for Tillamook Head was Nah-se-u—su.
TILLAMOOK Rock, Clatsop County. Tillamook Rock takes its name from Tillamook Head. It is famous because upon it is built Tillamook Rock lighthouse. An act approved June 20, 1878, made an appropriation of $50,000 for a first-class light on Tillamook Head. Subsequent appropriations of 1880-81 added $75,000 to this sum. The heavy cost of a road, and the fact that the light would be a thousand feet above the sea led Major G. L. Gillespie, U.S.A., then Light-House Engineer for the 13th District, to recommend a light on Tillamook Rock. An inspection was made of the rock, and H. S. Wheeler, superintendent of construction, was landed on the rock from the revenue-cutter Corwin on June 26, 1879. This was probably the first time a white man ever stood on the rock. An attempt by Wheeler to land on June 22 was a failure. John R. Trewavas, of Portland, a mason who had had experience in England working on lights, tried to land on September 18, 1879, to make a preliminary survey, but was drowned in the attempt. Construction was started in October. A little over 29 feet of rock was blasted off the pinnacle to provide a platform for the station. The rock was originally 80 feet high and a mile from shore, and had a sharp overhang to the west. All materials and supplies were landed by derricks.
