Smith, Ph.D. University of Nevada, Las Vegas December, 1993 ii Abstract The Tuff of Bridge Spring (TBS) is a regionally-widespread, andesite to rhyolite (59 .50 to 74.91 wt. %) ash-flow tuff of mid-Miocene age (ca. 15.2 Ma) that is exposed in the northern Colorado River extensional corridor of southern Nevada and northwestern Arizona. Determination of the areal distribution, geochronology, lithology, geochemistry, and internal stratigraphy of the TBS is important for its establishment as a reliable stratigraphic reference horizon for tectonic reconstructions of the extensional corridor during the middle Miocene.

Fifteen days were spent in the field and the methodology followed during the 1994 season was equivalent to that described in the earlier report. A complete species list is herein submitted along with a qualitative assessment of the vegetation. [For a detailed discussion of the climate, soils, and vegetation of the study site see Hogan (1993): A floristic survey of the Boulder Mountain Park. Natural History Inventory of Colorado, No. 13. Four hundred and seventy eight species of vascular plants in 324 genera and 97 families are documented for the Doudy Draw and Eldorado Mountain Area. Ninety species, nearly 19 % of the flora, are non-native. The largest families are Asteraceae (81 spp.), Poaceae (59 spp.), Fabaceae (26 spp.), Rosaceae (20 spp.), and Brassicaceae (19 spp.). This represents an additional fifty species from the 1993 report. None of the species added during the 1994 field season were species of special concern. The 478 species of vascular plants documented is evidence of the high species richness found along grassland-forest ecotones in western North America.
