Trails just don’t spontaneously appear. They are planned, built and blazed so people can travel safely from trailhead to summit and beyond. The purpose of a trail marker (or blaze) is to help hikers follow a given path. It is used to indicate things such as the beginning and end of a trail, a change of direction or an intersection.
Blazes are found on prominent trees that are easy to spot on the trail. They are usually placed just above eye level – or slightly higher in areas that receive snow. Painted markers are roughly two inches wide and six inches tall, while other types of markers and signs may vary in size.
