- Context
- Stained sediments from the cultural layer in main backhoe trench, 30-75 cm below the bladed surface. The date is from trenching in 2004 in the REX centerline, adjacent to the original trench for the prior pipeline. These later excavations in 2004 revealed this to be a natural paleosol referred to as the Spring Creek Paleosol; cultural materials recovered from the site primarily coincide with this paleosol. Thus, given a credibility of none since the date appears to be on a natural phenomenon.
