In 1933 the USGS remapped an area surrounding Crater Lake National Park and determined new elevations for Mount Bailey and Mount Thielsen, which are shown above. The elevation given for Mount McLoughlin was determined in 1904 by the USC&GS. The 1920 determination by the USC&GS is not used because it refers to the top of the lookout house and not the groundline. It should be noted that the Cascade Range extends well into California and includes both Mount Shasta and Lassen Peak.
CASCADE SUMMIT, Klamath County. Cascade Summit railroad station in the extreme northwest corner of the county, came into being with the completion of the Southern Pacific Cascade Line in 1925-26. The office is just east of the summit tunnel through the Cascade Range and got its name on that account. The elevation is 4841 feet. Cascade Summit post office was established September 8, 1927, with Oliver M. Shannon first postmaster.
CASCADES, Hood River County. The Cascades of the Columbia River were caused by natural obstructions. Lewis and Clark, 1805 - 1806, the first white men to see this geographical feature, used the word "cascades," but not as a name. The Upper Cascades they called "Great Shute." Alexander Ross, in his Adventures of the First Settlers on the Oregon, writing as of 1810-1813, mentions the cascades a number of times, indicating the obstruction in the river. David Thompson, of the North West Company of Montreal, on July 13, 1811, referred to "Rapids and Falls" and on July 27 to "Grand Rapid." John Work, of the Hudson's Bay Company, on June 22, 1825, wrote: "Embarked at 3 o'clock and reached the Cascades at 1." (Washington Historical Quarterly, volume V, page 85.) David Douglas, the botanist, in his journal for 1826 uses the word often, but not always for the same locality. Rev. H. H. Spalding, writing from Fort Walla Walla on October 2, 1836, uses the words: "The Cascades or Rapids." For an account of the fight with the Indians at the Cascades see OPA Transactions for 1896. The Cascades were submerged early in 1938 as a result of the construction of the Bonneville Dam.
CASCADIA, Linn County. This post office was so named because it was situated in the Cascade Range. It was established in 1898.
CASEY, Clatsop County. Casey post office was on Youngs River
