In this tutorial, I will be teaching you the basics of how to read and understand a topographic map. This is a skill that is critically important for anyone who plans on venturing out into the backcountry. Not only is it important that you always carry a paper, hard-copy map of where you will be going, but it’s also important that you know how to read it!

Today, I was talking to a friend, and it came to my attention that he was unaware of CalTopo. This individual in question is an avid off-trail explorer in The Red River Gorge. It blew my mind that he had never heard of what is probably one of the greatest mapping utilities ever made for the backcountry explorer! So, today we are going to right this atrocity and take a look at just what CalTopo is and how we can use it.
