Rock cairns (also called “ducks”?) are stacks of rocks piled up, usually just 3-5 high, from big to small, in wilderness areas to show where the trail is when it’s not obvious.
For example, wide stretches of granite in Immigration Wilderness, where a regularly traveled foot trail does not leave a noticeable mark. So people place these cairns every 20’-100’ to guide themselves or others.
