It is mostly on the south bank of a steep northwesterly- trending gully with its north end extending into bottom of the gully. The ground within the site descends steeply northeasterly from its south boundary into about the south one third to one half of the site then leveling out to the north end of the site. The site is currently undeveloped and is dotted by mature evergreen and deciduous trees and covered by thick underbrush. GEOLOGIC SETTING The Geologic Map of the Everett 7.5-Minute Quadrangle, Snohomish County, Washington, James P. Minard, published by U. S. Geological Survey in 1985, was referenced for geologic and soil conditions of the project site. According to this publication, the surficial soil units at and in the vicinity of the project site are mapped as Advance Outwash (Q,a) underlain by Transitional Beds(Qtb). The geology of the Puget Sound Lowland has been modified by the advance and retreat of several glaciers in the past one million years or so and the subsequent deposits and erosions. The latest glacier advanced to the Puget Sound Lowland is referred to as the Vashon Stade of the Fraser Glaciation which had occurred during the later stages of the Pleistocene Epoch and the last glaciers retreated from the region some 12,500 years ago. The deposits of the advance outwash soil unit are composed of stratified sand and gravel with very minor amount of silt and clay, deposited by the meltwater of advancing glacial ice of the last glacier then overridden by the still advancing glacier.
