The coolest map tool

And you thought the coolest map tool was one of those GPS units.

No.

This puppy is at the top of one of the minor peaks that is only a ten-minute hike from Trail Ridge Road, in Rocky Mountain National Park. If you line up your eye with a notch above the words along the edge - and the knob in the center, you will see that peak. The map tells both elevation of the peak and its distance from you.

Amazing.
