[Louis A. Brennan et al. (1962)] earth containing bones of extinct animals and an obsidian chip were cased together undisturbed and shipped to the Museum where the flake was removed in the presence of scientific witnesses. Mark R. Harrington of The Southwest Museum, Los Angeles, California, visited Tule Springs in October, 1933, on learning of Hunter's discovery, and went over the same ground. His party found several fire-ash beds with bones of extinct animals and choppers, scrapers, ovoids, and flakes. Samples of charcoal collected during this expedition and saved at the Museum was turned over to Dr. Willard Libby, the C14 dating technique discoverer, in 1952 and yielded, by the methods then in use, a minimum age of 23, 800 B.P., with the maximum not known. With this enhancement of the importance of Tule Springs, a small Southwest Museum expedition returned to the site in 1954, 1955, and again in 1956. Hearths and bones continued to appear, along with some artifacts. During the third or 1956 work session a fire pit or hearth was discovered in which there were burned bone and one worked stone tool, a discoidal scraper. This was the hearth that supplied the material for the latest C14 run, which yielded a new minimum date of 28, 000 years plus. Lab reports are that the maximum could be about 33,000 years. 2 THE BULLETIN The whole history of the site is told in The Southwest Museum publication "Tule Springs, Nevada, with Other Evidences of Pleistocene Man in North America" Southwest Museum Papers, No.
