Rock cairns as trail markers

This photo looks like a simple pile of rocks to the average person. But to others it is a "confidence builder," assuring them that they are on the trail! We're working on a book titled Safe in the Woods to help you learn these little tidbits to help you enjoy the great outdoors even more and, most importantly, safely.  By the way, "cairn" is pronounced "Kern." More on them in the book.
