Skyline Mechanics Study

Purpose

Summer 1985: We will be conducting static tests on the skyline corridor. Measuring skyline and guyline loadings, and tailtree deflections. Summer 1986: Dynamic tests will be conducted on the skyline corridor.

Tailtree Mechanics

Purpose

We will be rigging a short (<400'] skyline corridor and "logging" less than the equivalent of 20 trees (hardwoods mostly) to measure the dynamic behavior of the tailtree.

Sharptail Snake Survey Methods

Purpose

To distribute wood "placements" in meadow and then look under them 2-4 times during March-May to see if any sharptails snakes have taken refuge under these boards. No animals will be removed. Any sharptails will be photographed where they are found. Th
