One of the site's unusual features is a series of pits that were apparently used for leaching tannin from acorns. These pits, as well as associated features, including basketry weave patterns, bear resemblance to finds at other sites on the Pacific coast of North America, and in Japan, representing a rare direct connection between North American and Asian cultures.[5]
The site has been a site of interest to amateur collectors since at least the early 20th century, and came under further threat in the late 20th century by seepage from a nearby levee. It was also threatened in 2008 by potential engineering work that may damage the site, in order to support an earthen dam.[4]
