Age. Late Wisconsin. Brasso and Emslie (2006) reported a date on Gymnogyps californianus of 10,795 ± 50 (CAMS 123881) or 25,090 ± 220 (CAMS 123916). One of these dates is from Sandia Cave and one from Marmot Cave; however, which belongs to which cave is uncertain from the publication since the abstract gives one result and the text the other.
General Description. Approximately 100 m north of Sandia Cave (which see). Also known as Davis Cave (Brasso and Emslie 2006).
Discussion. Thompson and Morgan (2001) noted that the extralimital mammalian fauna generally occurs at elevations over 3000 m in the northernmost mountains of New Mexico, inhabiting montane and subalpine coniferous forests. However, most reach considerably lower elevations, especially in northwestern New Mexico and adjacent Colorado (Harris 1963). Nevertheless, the fauna does signify a colder temperature with more effective precipitation than now occurs at the elevation of Marmot Cave.
