Davis Strain Grid Measurement 1971

Strain grid measurements near Davis during the traverse program for the 1971 season. Chaining out from the center pole to one of four corner stakes required two moves with an assumed 600ft "invar" tape. Measurement in both directions was achieved on all grids. Snow to bottom of tag measurements were recorded in centimeters plus the central two inch steel black pole.

For the theodolite readings, both left and right face azimuth angles were taken at snow level and elevation read to the bottom of the tag.
