Google Maps and GPS tracking apps are of great assistance when hiking in the wild, but they still fall short when it comes to identifying distant landmarks such as mountains and peaks.

A clever solution to the problem is a “viewing tube” consisting of a metal tube welded to a rigid object, such as a pole, and pointing towards the distant landmark. When a viewer peers through the tube, he sees the landmark through the other end. Ingenious, isn’t it?

This is what a viewing tube looks like.
