Selah Ridge, Washington
During my walk to the top of the cherry orchard I found a new way to get up to the top of Selah Ridge that overlooks the hillside where we live. There are so many places around our neighborhood to explore. The trek to the top of the ridge from here will be one that I plan to wander and explore.
Looking at this line of basalt rock, I ask myself how this remnant of a lava flow got way up here. Beneath this level of basalt lay strata of limestone-type sediments from an ancient sea bed. How did a sea bed get up here? Piecing the little that I know of the geologic history of the area, the following is what I think happened: First, this area at one time was under the Pacific Ocean. Then the volcanic Cascade Mountains were formed which separated Eastern Washington from the coastal plain. Later, the Eastern Washington, Eastern Oregon, Southern Idaho basalt flows covered what is now the Columbia Basin. Then the moving continental plates slowly forced up the Yakima Folds creating a line of ridges across south central Washington. We live at the base of one of these ridges.
