How it works

Reading the scale: at 1:40,680, 1 in on the map is about 0.64 miles on the ground, which leaves room for trail junction mileages and contour detail.

UTM grid: the grid lines let you read a coordinate off the paper map and match it to a GPS unit or phone set to UTM, or plot a GPS position back onto the map.
