Individuals were divided into front of this document may be used as an overlay. Furthermore, the ecosystems and wildlife populations that constitute an important part groups to address specific geographic regions. They used map report was drafted in a manner to allow each individual chapter to be of Arizona’s wealth. In particular, roads, urbanization, canals, transparencies and tailored questionnaires to assist in the used as a stand-alone tool. For that reason, terminology common railways, energy corridors and activities of illegal migrants and identification of habitats, wildlife species, wildlife behavior and throughout the entire document is defined in each section.

The first one consists of a series of intercalations of calc-silicate rocks, local marbles, and greenschist. Quartzite appears in the upper part of the section. This section passes transitionally to the gneiss, which is believed to be of sedimentary origin. Features indicative of sedimentary origin include inter­ calation with marble, relic bedding which can be observed locally, intercalation of greenschist clearly of sedimentary origin, lack of homogeneity in composition with both lateral and vertical variation occurring, roundness of zircon grains, and lack of zoning in the feldspars.

ISSN 2153 733X AJO PEAK TO TINAJAS ALTAS: A FLORA OF SOUTHWESTERN ARIZONA Part 6. POACEAE – GRASS FAMILY RICHARD STEPHEN FELGER Herbarium, University of Arizona Tucson, Arizona 85721 & Sky Island Alliance P.O. Box 41165, Tucson, Arizona 85717 *Author for correspondence: [email protected] SUSAN RUTMAN 90 West 10th Street Ajo, Arizona 85321 JIM MALUSA School of Natural Resources and the Environment University of Arizona Tucson, Arizona 85721 [email protected] ABSTRACT A floristic account is provided for the grass family as part of the vascular plant flora of the contiguous protected areas of Organ Pipe Cactus National Monument, Cabeza Prieta National Wildlife Refuge, and the Tinajas Altas Region in southwestern Arizona. This is the second largest family in the flora area after Asteraceae. A total of 97 taxa in 46 genera of grasses are included in this publication, which includes ones established and reproducing in the modern flora (86 taxa in 43 genera), some occurring at the margins of the flora area or no long known from the area, and ice age fossils. At least 28 taxa are known by fossils recovered from packrat middens, five of which have not been found in the modern flora: little barley ( Hordeum pusillum ), cliff muhly ( Muhlenbergia polycaulis ), Paspalum sp., mutton bluegrass ( Poa fendleriana ), and bulb panic grass ( Zuloagaea bulbosa ). Non-native grasses are represented by 27 species, or 28% of the modern grass flora.

Similar declines were noted in Sonora, Mexico; however, the species still persists at many sites in Mexico. Chytridiomycosis was detected during some declines and implicated in others; however, airborne pollutants from copper smelters, predation, competition, and extreme weather may have also been contributing factors. We collected Tarahumara Frogs in Sonora for captive rearing and propagation beginning in 1999, and released frogs to two historical localities in Arizona, including Big Casa Blanca Canyon and vicinity, Santa Rita Mountains, and Sycamore Canyon, Atascosa Mountains.

At issue are impacts that may result from the proposed reauthorization of livestock grazing on the Sentinel, Cameron, Childs, Coyote Flat, and Why allotments located in Maricopa and Pima counties, Arizona. The Bureau of Land Management (BLM) has determined that the proposed action for the five allotments may adversely affect the endangered Sonoran pronghorn (Antilocapra americana sonoriensis), and the proposed action for the Cameron and Childs allotments may adversely affect the endangered cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum). In your letter, you also requested our concurrence that the proposed action on the Cameron, Childs, Coyote Flat, and Why allotments may affect, but will not likely adversely affect, the endangered lesser long-nosed bat (Leptonycteris curasoae yerbabuena). We concur with that determination, which is based on sound analysis and guidance criteria for the species mutually agreed upon by our agencies.

    Cabeza Prieta Natural History Association A Visitor's Guide to El Camino del Diablo Leg 2a: Darby Well Road to Tule Well "You can't see anything from a car; you've got to get out of the ... contraption and walk, better yet crawl, on hands and knees, over sandstone and through the thornbush and cactus. When traces of blood begin to mark your trail you'll see something, maybe." Ed Abbey, Desert Solitaire Mile 0.0. 32° 21’21.5”N, 112° 49’37.5”W. Key Junction. Hwy 85 at Darby Well Road to Bates Well. Take a moment here to double check that your gas gauge reads "full," your tires have air, and the ice chest is stowed for a bumpy ride. No services from here to Yuma; 130 miles of bad road lie ahead. Reset odometer. Make sure that you have your Cabeza Prieta range permit from https://luke.isportsman.net and that you check in by phone with Goldwater-West to give them your permit number or use the website http://www.rangeaccess.com/RangeAccess.aspx. The Goldwater number is on the back of your permit, but Darby Well Road may be your last reliable phone connection. Black Mountain (3,008 feet), standing to left of the road ahead, is an eroded remnant of a basaltic volcano that once covered a much larger area. The horizontal banding is due to differences in hardness between the basalt flows and softer tuffs that have been tilted and faulted. The brown- black color tinged with red is typical oxidation and weathering for such rocks.

    Gold Deposits Near Quartzsite, Arizona

    GOLD DEPOSITS NEAR QUARTZSITE, ARIZONA. By EDWARD L. JONES, Jr. INTRODUCTION. This report is based on information obtained by the writer in April and May, 1914,. while he was classifying the lands in the Colorado River Indian Reservation. The area considered includes the south­ ern part of the reservation and the region extending eastward from the reservation to the Plomosa Mountains. The geology and ore deposits within the reservation were more particularly studied, the time allotted to the examination being too short to permit detailed work in the area farther east. For information concerning placers outside the reservation the writer is indebted to Mr. E. L. Du- fourcq, who conducted the testing of placer .ground near Quartz- site. Mr. W. W. McCoy, of San Bernardino, kindly furnished the early history of the La Paz district, and Mr. Edward Beggs, of Quartzsite, gave much useful information regarding the La Paz placers. In 1909 Howland Bancroft x made a geologic reconnaissance of northern Yuma County .and much of the country around Quartz- site and farther west to the reservation line. In his report he men­ tions the La Paz district and briefly describes placers in the Plomosa Mountains and prospects on gold-bearing quartz veins in the vicinity of Quartzsite. The map that accompanies the present report (PI. IV) is compiled from the records of the General Land Office. The area within the reservation has been subdivided into sections; the land east of the reservation is unsurveyed. The mountainous areas in the reserva­ tion are indicated on this map by patterns showing the geologic rock formations; the mountains in the unsurveyed area are repre­ sented approximately by hachures.
