Cultural Period: Ancestral Puebloan, Atsinna Pueblo (A.D. 1275 – mid-1300s)
Description: This mount contains the remains of three different perishable artifacts. The upper left is a rim fragment of a wicker basket. Laurie Webster, of the University of Arizona, describes this basket as having a 1/1 interlaced weave structure with a multiple-element warp, and a rim selvage with 360 degree wrapping around a group of perhaps four twigs. Each warp twig is 1.5 - 1.8 mm in diameter, and the warp channel is approximately 2.0 cm wide. The weft consists of a single twig, 1.0 mm in diameter. There are eight rows of weft per cm.
The second artifact (bottom left) consists of the partial base of a wickerwork basket identified by Laurie Webster as having a 1/1 interlacing weave structure with a multiple-element warp. Of the six warp channels in the outermost row of the basket, three contain two twigs and four contain three twigs. The average width of the warp channels is 2.0 cm. The diameter of each warp twig is approximately 2.0 mm, and each weft twig is between 1.5 and 2.0 mm. The basket has seven weft rows per cm. Archaeobotanist Karen Adams identified the raw material as possibly oak (Quercus sp.). A brown substance with off-white specks adhering to the upper surface of the basket may be food residue.
The fragments on the right are part of a large, deteriorated, consolidated mat-like object. Laurie Webster identified the weave structure as 1/1 plaiting, and Karen Adams identified the raw material as five-to-ten year old split oak (Quercus sp.) stems. The warp elements are 4.0-6.0 mm in diameter and spaced about 2.0 cm apart, and the weft elements are about 6.0 mm wide and spaced about 2.0 cm apart.
Dimensions: 4.5 cm-long by 5.5 cm-wide (upper left); 7.3 cm by 11.0 cm (bottom left); 9.0 cm long and 21.0 cm wide (largest fragment on the right).
