Dry Tilt Activity 13. In the 1980s geologist developed a second method to calculate tilt.
Dry tilt uses precise surveying techniques and trigonometry to calculate a tilt vector.
This activity outlines the steps followed to calculate the tilt vector. The vector is then plotted and its significance interpreted. Dry tilt stations are designed to approximate equilateral triangles with one vertex at the south. Two sets of readings are listed below. Use the reading to determine the change in elevation along each side of the triangle.
