  • A horizontal notch cut well into a tree at about breast height. In a cadastral survey, two hacks are cut to distinguish them from other, accidental marks. A vertical section of the finished hack marks resembles a double-V extending across a tree from two to six inches, depending on the diameter of the tree. The “blaze” and “hack” marks are equally permanent, but so different in character that one mark should never be mistaken for the other. Hacks are sometimes called “notches” or, in older surveys, “chaps.”
