Natural Markers: Cairns, Ducks, and Tree Marks
Cairns in alpine or desert landscapes indicate the safest line over bedrock. Follow existing, purposeful stacks spaced like breadcrumbs; never build decorative towers that confuse others. In storms, cairns can be lifelines. If your area uses them, share spacing patterns you’ve observed to help travelers anticipate gaps.
Natural Markers: Cairns, Ducks, and Tree Marks
Some forests use small, official cuts or paint on trunks. Do not carve new marks; it harms trees and misleads hikers. Learn to recognize aged paint or scribed rectangles that still indicate the corridor. If you’re unsure whether a mark is official, ask local stewards or post a photo for identification.
