This is the annual report from the investigators responsible for soil
characterization at the Findley Lake watershed. Soil characterization
is complete for two soils and is in progress on six others. Site
preparation for years 3 and 4 is complete except for lysimeter
installation.
Findley Lake watershed is located in the Snoqualmie National Forest and has a surface area of 259 ha (1 Mi²). The lake is at an elevation of 1128 m (3701 ft) but the ridges attain elevations of 1450 m (4750 ft).
The Cougar Mountain Formation, consisting of lava flows, conglomerate,...
One of the major objectives of the Western. Coniferous Biome is to understand the relation between terrestrial ecosystems and the chemical and biological properties of drainage waters. The first year of study on such a program has been completed and has primarily entailed a year of descriptive studies.
Data on soil temperature at two locations and five depths, tensiometer readings, and soil moisture release curves for the soils of Findley Lake are presented in this report.
On 20 March 1972 three snow cores and one surface snow sample were taken on the Findley Lake watershed to obtain a preliminary estimate of the elemental composition of the snowpack. Variation in chemical composition
with depth and between forested and open areas was also investigated. Data from Ca²⁺, Mg²⁺,...
