Geotechnical Engineering: Particle Size Distribution Of Layered Glacial Lake Columbia And Ice Age Flood Deposits In Latah Valley, Spokane, Wa, Aaron Cleveland, Kassie Allen
2020 Symposium Posters
We collected samples from the Latah Valley in Spokane, WA, of Missoula Flood deposits interbedded with Glacial Lake Columbia Sediments. We conducted tests on these soils according to ASTM standards. We performed Specific Gravity tests according to ASTM D854, and determined particle size distribution for these soils by conducting sieve and hydrometer analyses according to ASTM D422. We then plotted these data to create particle size distribution curves. Specific Gravities for the all of the samples collected range from 2.36 to 2.67. The flood deposits are dominated by coarse sand and gravel and the Glacial Lake Columbia deposits are dominated …
