2023-04-29 Skye Cooley — Soil-climate evidence for timing of the Cascade uplift and creation of its rain shadow
Skye Cooley, independent geologist from Montana, will be presenting an interesting story about timing of the Cascade uplift and creation of its rain shadow as evidenced by the presence and distribution of arid-land soils, specifically calcic soils and calcretes in eastern WA. Skye has been working on this subject for several years and has visited hundreds(?) of outcrops. The presence of the calcretes touch on the timing of the Cascades’ rise (dry climate info), growth of Yakima Fold Belt uplifts (paleoslope info), and ancient glacial floods (stratigraphic info). The lecture will be on Saturday, April 29th and is our second post-Covid in-person lecture. We’ll… Read more2023-04-29 Skye Cooley — Soil-climate evidence for timing of the Cascade uplift and creation of its rain shadow
