  • Location Description: This description was taken on a nearly level loess summit in the southwestern portion of Spokane Co. This site appears to have been affected by the missoula floods, as evidenced by the rounded rocks in the soil profile. The 1968 soil survey mapped this site as a fine-silty, mixed, mesic, superactive pachic haploxeroll.
