Debris‐flow activity in the Santa Catalina Mountains in July 2006 dramatically illustrated the potential for sizable debris flows to exit canyons along the mountain front and the potential for adverse impacts to properties near canyon mouths. The purpose of this study was to map the extent of prehistoric debris‐flow deposits at the mouths of selected Santa Catalina Mountain canyons in eastern Pima County. Arizona Geological Survey (AZGS) geologists mapped the extent of latest Pleistocene to Holocene debris‐flow deposits along channels at the mouths of 15 canyons. In late 2007 the scope of work was expanded to include mapping of modern (2006) debris‐flow deposits in Soldier Canyon, and to delineate the downstream extent of these deposits in other canyons. United State Geological Survey (USGS) geologists collected wood and rock samples from selected paleodebris‐flow deposits to date deposit‐ages using radiocarbon and cosmogenic dating techniques. This report summarizes our findings and describes the mapped debris‐flow deposits depicted on accompanying map sheets. 11 maps found in Digital Map Series 1A-1K 1:6,000Additional Links

Ecology of riparian breeding birds along the Colorado River in Grand Canyon, ArizonaThe density, diversity, and nest-site selection of riparian breeding birds were studied from 1982 to 1985 in mesquite (Prosopis glandulosa) and tamarisk (Tamarix chinensis) communites along the Colorado River in northern Arizona. Avian density in tamarisk communities was significantly greater (P=0.052 and 0.024 in 1984 and 1985, respectively) than avian density in native mesquite communities with similar vegetative cover and height attributes. Avian diversity was similar in both communities. Breeding bird densities in tamarisk were higher than those reported from other geographic areas. Vegetation structure and shrub species composition were measured at nest sites of eleven species of riparian birds in a tamarisk community to examine avian habitat relationships. Riparian birds exhibited differences in their choice of nesting habitat. Discriminant analysis indicated that Bell's Vireo (Vireo bellii), Yellow Warbler (Dendroica petechia) and Yellow-breasted Chat (Icteria virens) were relative generalists in nest site selection, while Common Yellowthroat (Geothlypis trichas) and Northern Oriole (Icterus galbula) were relative habitat specialists. Bell's Vireo and American Coot (Fulica americana) nested in habitats that were the most different. Willow Flycatcher (Empidonax traillii) and Yellow Warbler nested in habitats that were the most similar. Willow Flycatcher and Yellow Warbler consistently used habitat most similar to that used by all other species. Nest placement preferences of six riparian passerines were examined in the tamarisk community to test the null hypothesis that nest placement in any given species of shrub was random. Ninety-five of 105 nests sampled were located in tamarisk. Five of the six species of passerines exhibited a significant preference for tamarisk for nest placement. A highly significant preference for tamarisk was shown by the four species with the smallest median frequency of tamarisk in their nesting habitat. The usefulness of tamarisk for nest placement was higher than that reported from other areas.
