Throughout the Aleutian Islands, gravesites have been found that are above-ground sarcophagi. These sarcophagi are left exposed, with no attempt to bury the dead in the ground. These burials tend to be isolated and limited to the remains of adult males, which may indicate a specific ritual practice. In the Near Islands, isolated graves have also been found with the remains, and not just the sarcophagus, left exposed on the surface. This way of erecting sarcophagi above ground is not as common as umqan and cave burials, but it is still widespread.
