The Hawaiian Volcano Observatory asks visitors to say “no” to rock piles after a surge in the creation of cairns by visitors. The construction of these rock formations comes at the cost of important geological features that visitors pry rocks off of. The practice is viewed as an act of graffiti on the landscape of the park.

Elements often found at these sites include dry stone walls, rock piles (sometimes referred to as cairns), stone chambers, unusually-shaped boulders, split boulders with stones inserted in the split, and boulders propped up off the ground with smaller rocks.
Rock piling in streams silts the water, disrupts critical habitat, and can kill rare wildlife. In a river in Pisgah National Forest, scientists have repeatedly found protected Eastern hellbender salamanders crushed under the piles of rocks that tourists build midstream. In addition to the direct killing that takes place while the rocks are ...
A pillar is a landform, either of rock or earth, defined by the USGS as: "Vertical, standing, often spire-shaped, natural rock formation (chimney, monument, pinnacle, pohaku, rock tower)." [ 1 ] Some examples of rock pillars are Chambers Pillar , Katskhi pillar , Pompeys Pillar , and Pillar Rock .
In some instances, rocks are aligned near the entrance and fire of sweat lodge ceremonies that symbolize the Moon, the Sun and other things. Rock piles are still made to mark trails and important locations. A large turtle petroform of piled up boulders was recently made in the Whiteshell Park area of Manitoba. [citation needed]
An effigy mound is a pile of earth, often very large in scale, that is shaped into the image of a person or animal, often for symbolic or spiritual reasons [7] An enclosure is a space that is surrounded by an earthwork. [8] Long barrows are oblong-shaped mounds that are used for burials. [9] A tumulus or barrow is a mound of earth created over ...
Talus deposits typically have a concave upwards form, where the maximum inclination corresponds to the angle of repose of the mean debris particle size. [8] Scree slopes are often assumed to be close to the angle of repose. This is the slope at which a pile of granular material becomes mechanically unstable.
In the archaeology of the United States and Canada, a mound is a deliberately constructed elevated earthen structure or earthwork, intended for a range of potential uses.In European and Asian archaeology, the word "tumulus" may be used as a synonym for an artificial hill, particularly if the hill is related to particular burial customs.
