Quicksand is often misunderstood as a deep pit, but it's actually a mixture that appears solid. When stepped on, the mixture loses its solidity and becomes fluid. Struggling in quicksand makes it even more fluid. Research indicates that quicksand won't completely engulf a person.

A person who got stuck in quicksand during a trip shared their experience. This incident occurred while they were on a canyoneering trip with friends. The person is a professional guide.

Further details about quicksand and the guide's experience are available from the source, including videos of the canyon floor.
