Rockfalls, also known as rockslides, are events in which rocks or boulders detach from a steep slope or cliff and fall to a lower level. Other common synonyms for rockfalls include rock avalanches, rock tumbles, and rock cascades. These events can be triggered by a variety of factors, including erosion, weathering, seismic activity, and human activities. Rockfalls can be dangerous and have the potential to cause property damage, injuries, and fatalities. As such, it is important to take precautions when visiting areas with steep slopes, such as wearing appropriate footwear and paying attention to warning signs and advisories from park rangers and other authorities.
