Westward Ho! How Far is Yonder Mountain
Initial Publication Date: June 28, 2006
Summary
One of a collection of PowerPoint/Excel modules designed to reinforce quantitative skills in geologic context. Students build a spreadsheet to calculate the distance of a peak using vertical angles sighted from a wagon train heading directly for the peak. The spreadsheet also calculates the height of the peak above the plain.
Learning Goals
Students will:
- Gain experience in figuring out how to solve a trigonometric problem in geologic/geographic context.
- Develop a spreadsheet to carry out a calculation.
- Consider the effect on the calculated answer of small uncertainties in the measured quantities.

Context for Use
This activity was designed for an upper-division math-in-geology course for geology majors but can easily be used in an introductory undergraduate geoscience class, as well as a high school trigonometry class.
Description and Teaching Materials
