NM: Roosevelt Co., Ca. 1,280 M.
General Description.—For overall description of locality, see Blackwater Loc. No. 1, above. The Gray Sand is the eariest unit of pond sediments. Hester (1972) cites Haynes as believing it is full pluvial, between 13,000 and 25,000 BP. Average thickness is 3 ft. Deposits suggest a time of ample and steady water supply. Haynes is cited as emphasizing possibility that Clovis artifacts and some bones may have come from above due to roiling action of feeder springs, etc.
Comments.—Summary of work at Blackwater Loc. No. 1 in Hester, 1972. Fauna from the gray sand level by Lundelius, 1972 (in Hester, 1972). Lundelius cites earlier work on the gray sand by Stock and Bode (1937) who reported most of the species. "Speckled sand" of Stock and Bode (1937) is the gray sand of later stratigraphy (Hester 1972). The specimen of cf. Geochelone is thought by Lundelius (1972) to have been reworked from older deposits; preservation is different than other gray sand specimens, etc. I have a margin note in the publication that the specimen of Canis dirus was reconsidered by Lundelius and that in 1978 he considered it to be C. lupus. The note is based on communication from E. Johnson.
Age.—Probably >15,000 BP (Haynes and Agogino 1966).
