Rectification (or how to use some visible landmarks to triangulate your own position)
You have a map and your compass, and you're "somewhere" out in the wilderness.
After orienting your map to true north, you can identify Eagle Mountain and Fiddler Mountain "in the real world."
The bearing of Eagle Mountain is 13 degrees.
The bearing of Fiddler Mountain is 92 degrees.
Using the map below, locate your approximate position, and represent it in UTM UPS coordinates (you may want to print the map, though you can work off your computer display without marking on it (!) using "trial and error").
You can click on the map to enlarge it and repeat for an even larger image.
