Sitka Sound Striations

Proposed by Jim Baichtal on a March 2014 visit to Sitka, the purpose of this project is to collect observations of glacial striations in/around Sitka Sound. The goal is to get a better sense of the movement and extent of glaciers in this area during the last glacial maximum. At its simplest, documenting these striations requires recording the coordinates (which can be selected from a map on the form) and noting the azimuth (direction) of the scratches, which requires a compass. Note also that the current declination in the Sitka Sound area is about 20 degrees East.
