- Feature 12, a bell shaped cist in the NW part of Room 3, Component 1, Block 3. The upper part of the cist had partially collapsed, thus the size of the opening is unknown. The cist was 141-143 cm deep. The sides narrow to an opening ca. 70 cm in dia. at a depth of 85 cm below the floor of Room 3, then open to a maximum dia. of 120-97 cm ca. 15 cm above the floor of the cist. Fill was brown clayey silt, with bits of charcoal and burned adobe throughout. It is possible that Feature 12 predates Room 3 and is the easternmost of an arc of cists located to the N of, and assoc. with Pit Structure 2. A similar situation was found in Block 4. C14 sample was on charcoal from the bottom of Feature 12.
