The chamber was placed at the extreme top of a hillside. Its tunnel entry is set to the far north side. It is walk-in chamber that is the height allows a person to walk upright into the chamber room. The room is spacious. Its size suggests two people may have occupied the inside during a ceremony.
The loose tobacco offering is recent, showing Native Americans are still using the chamber.
Chambers are generally built underground. Underground can be a natural embankment like this chamber or a mounded embankment like the Wendell Twin Chamber. Either way the embankment or mound, places the chamber underground. Underground is the Underworld. A person entering a chamber therefore enters the Underworld, a sacred place.
A short distance away is good size on ground cairn and several on stone cairns were seen. They are close enough to be an extension of the site that includes the chamber.
