Geographical Description.
Clealum is situated on the Yakima River, at a point on the Northern Pacific Railway, 122 miles east of the humid, heavily forested coast at Puget Sound. Although situated not over 154 miles from Copalis, on the ocean at the western edge or furthest limit of the temperate humid coast country, the summers are hot and dry and the winters severe. It is 1909 feet above the sea level and far enough towards the summit of the Cascade Mountains, that marks the line between the humid coast and the arid almost treeless interior, to find considerable moisture and many trees.
Ellensburg is situated near the eastern side of the Yakima River, 25 miles below Clealum, at an altitude of 1512 feet above the sea level and in the wide somewhat flat Kittitas Valley which was, in former geologic times, a lake bottom. The river flows rapidly and its low banks at places are high enough to form gravel bluffs. The surrounding country is arid and there is no natural forest growth.
Cherry Creek, one of a number of small streams on this side of the river, flows through the eastern part of this valley, and empties into the Yakima River about one mile below Thrall on Section 31, Town 17, North of Range 19 East. Here, the river enters Yakima Canon which cuts through Umptanum Ridge and the western foothills of Saddle Mountains. There are some pines in this canon.
Selah Creek flows through Selah Canon from the east and empties into the Yakima, about one mile above Selah at the northwest corner of Section 16, Town 14, north of Range 19 East. This is in a broad valley below Yakima Canon. At the time of our visit, however, the lower portion of this creek was dry. Wenas Creek empties into the Yakima from the west, nearly opposite Selah.
North Yakima is on the western side of the Yakima River, about two miles below the mouth of the Naches, which empties into the Yakima from the west, immediately below where the latter breaks through Yakima Ridge. This break is called the Gap or the Upper Gap. North Yakima is at an altitude of 1067 feet above the sea level. The soil of the valley is made up of a rich volcanic ash and the region is arid and practically treeless except on the banks of the rivers and creeks or where irrigation has been successfully practised. The climate in most respects resembles that of the southern interior of British Columbia, lying to the north, but in general, there is less vegetation except on irrigated land.
