In 1996 University of California, Riverside anthropologist R. Ervi Taylor examined seventeen of the Spirit Cave artifacts using mass spectrometry. The results indicated that the mummy was approximately 9,400 years old (uncalibrated Radio-Carbon Years Before-Present (RCYBP); ~11.5 Kya calibrated) — older than any previously known North American mummy.

Tule....
Schoenoplectus acutus (syn. Scirpus acutus, Schoenoplectus lacustris, Scirpus lacustris subsp. acutus), called tule common tule, hardstem tule, tule rush, hardstem bulrush, or viscid bulrush, is a giant species of sedge in the plant family Cyperaceae, native to freshwater marshes all over North America.
The common name derives from the indigenous Mexican word tullin (Nahuatl=bulrush), and was first applied by the early settlers from New Spain who recognized the marsh plants in the Central Valley of California as similar to those in the marshes around Mexico City.
