W.; Hoffer, J. M.; Callender, J. F.; [eds.], New Mexico Geological Society 31st Annual Fall Field Conference Guidebook, 308 p. This is one of many related papers that were included in the 1980 NMGS Fall Field Conference Guidebook. Annual NMGS Fall Field Conference Guidebooks Every fall since 1950, the New Mexico Geological Society (NMGS) has held an annual Fall Field Conference that explores some region of New Mexico (or surrounding states). Always well attended, these conferences provide a guidebook to participants. Besides detailed road logs, the guidebooks contain many well written, edited, and peer-reviewed geoscience papers. These books have set the national standard for geologic guidebooks and are an essential geologic reference for anyone working in or around New Mexico. Free Downloads NMGS has decided to make peer-reviewed papers from our Fall Field Conference guidebooks available for free download. Non-members will have access to guidebook papers two years after publication. Members have access to all papers. This is in keeping with our mission of promoting interest, research, and cooperation regarding geology in New Mexico. However, guidebook sales represent a significant proportion of our operating budget. Therefore, only research papers are available for download. Road logs, mini-papers, maps, stratigraphic charts, and other selected content are available only in the printed guidebooks.

Greater Big Bend International Dark Sky Reserve WHITE PAPER July 1
Greater Big Bend International Dark Sky Reserve WHITE PAPER July 1, 2020 I. Introduction McDonald Observatory is applying to the International Dark-Sky Association (IDA) to establish an International Dark Sky Reserve (DSR) in the Big Bend region of far West Texas and Northern Mexico. Such certification will help raise awareness of the value of protecting the night skies for ongoing astronomical research at the Observatory and encourage communities in the area to adopt night sky friendly outdoor lighting practices. Such practices create a safer and more attractive nighttime environment, promoting eco- and astro-tourism in the region. Also, mitigating the amount of artificial light shining wasted into the night sky helps protect major wildlife habitats and migration corridors throughout the Big Bend. II. McDonald Observatory McDonald Observatory is a 500-acre satellite campus of the University of Texas at Austin, located in the heart of the Davis Mountains in far West Texas. This world-class astronomical research facility is home to some of the world’s largest telescopes and darkest night skies. The Observatory maintains a robust public outreach program, including Guided Tours of its research facilities, evening Star Parties three times a week, accredited teacher workshops, and live- streaming telescopic tours of the night sky, the Moon, and the Sun. III. Greater Big Bend International Dark Sky Reserve An IDA International Dark Sky Reserve is a public or private land possessing an exceptional or distinguished quality of starry nights and nocturnal environment that is specifically protected for its scientific, natural, educational, cultural, heritage and/or public enjoyment. Reserves consist of a core area meeting minimum criteria for sky quality and natural darkness, and a peripheral area that supports dark sky preservation in the core. -

Ecology of the Mountain Lion on Big Bend State Park in Trans-Pecos
Ecology of the Mountain Lion on Big Bend Ranch State Park in Trans-Pecos Texas August 1, 1999 Ecology of the Mountain Lion on Big Bend Ranch State Park in the Trans-Pecos Region of Texas FINAL REPORT Wildlife Division Research Study Project Number 86 By Michael T. Pittman Gilbert J. Guzman Billy Pat McKinney November 1, 2000 Ecology of the Mountain Lion on Big Bend Ranch State Park in the Trans-Pecos Region of Texas 1 Abstract Twenty-one mountain lions (Puma concolor) were captured on Big Bend Ranch State Park (BBRSP), 18 December 1992 - 31 August 1997, using leghold snares or trained hounds. Captured lions were examined and aged, and morphological measurements were recorded. Sixteen lions were fitted with radio transmitters operating on individual frequencies. Collared lions were monitored from the ground and fixed-wing aircraft. One radio failed to work, but a total of 711 locations was recorded for 10 male and 5 female radio-collared mountain lions. Home ranges were delineated for 6 male and 5 female lions. Average annual ranges (100% minimum convex polygon) for adult male lions (348.6 km2 or 86,140 acres) were 59.1% larger (P<0.05) than for adult female mountain lions (205.9 km2 or 50,878.8 acres). Average percent overlap (100% minimum convex polygon) of annual female-female, male-male, and female-male lion ranges were 26.1, 22.9, and 28.9, respectively. Annual shifts were apparent (P<0.05) for female lions and for the cumulative male mountain lion ranges. Analysis of fecal scats (n=135) indicated collared peccary (Tayassu tajacu) and mule deer (Odocoileus hemionus) were preferred prey and were consumed almost equally. -

(i.e., translocated animals released immediately onto landscape) or 2) soft-release (i.e., released into an enclosure for an acclimation period before being released onto the landscape). Soft-release is usually preferred because it is thought to maintain site fidelity and aid in post-release survival, although it has been documented that some species do not benefit from this. -

Big Bend Ranch
TEXAS PARKS AND WILDLIFE BIRDS OF BIG BEND RANCH STATE PARK AND VICINITY Including Lajitas, Redford, Presidio, Ruidosa, Candelaria, Shafter, Casa Piedra and Terlingua; also Chinati Mountains State Natural Area A FIELD CHECKLIST 2011 Cover: Illustration of Black-tailed Gnatcatcher by Jeremy Boehm. INTRODUCTION ot to be confused with the similarly named national park to the east, Big Bend Ranch State Park, located in Nextreme southeastern Presidio County, encompasses 280,000 acres of vast Chihuahuan Desert habitat including grasslands, desert scrub, canyons, riparian woodlands and thickets, streams, rivers and numerous permanent springs. The bulk of the park includes the Bofecillos Mountains, an extinct volcano, and its outlier alluvial fans that form a mountainous plateau averaging 4,000 feet elevation. As such, the major- ity of the landscape is dominated by igneous soils and rock; however, a number of areas include outcrops of sedimentary rock (limestone) especially along Cienega Creek in the north- western portion of the park. A prominent feature of the park is The Solitario, a col- lapsed volcanic dome or lacolith, approximately 10 miles in diameter, which pushed up several concentric geologic layers that are now exposed through the harsh actions of erosion. Overall, the geology of the park is as diverse as any comparable location in the United States. The climate of the area is warm to hot year-round; rainfall averages 8-10 inches per year, most of which (approximately 75%) falls during the late summer/ early fall monsoon season. The lowest elevation in the park is near Lajitas (approximately 2,300'), where the Rio Grande continues its pathway southeastward. -

Plata Ranch 173.1 Acres, Presidio County, Texas
Plata Ranch 173.1 acres, Presidio County, Texas 432-386-2821 Cell 432-426-2024 Office [email protected] Plata Ranch History, Water, and Compound 173.1 Acres, south of Marfa, Presidio County, Texas James King, Agent Office 432.426.2024 [email protected] Location Plata Ranch, located 30 miles south of Marfa and fronting on paved Casa Piedra Road or FM 169, is a jewel embedded in a scenic landscape of large ranches at the gateway to Big Bend Ranch, located further to the south. Amenities of Marfa are just a 30-minute drive along paved scenic paved road. Plata’s history began with some of the earliest Spanish Settlements in Texas in the late 1700’s on the banks of Alamito Creek and was a vibrant western outpost with abundance of water, growing vegetables and orchards for the mines at Shafter to the west. The Atchison, Topeka and Santa Fe Railway is across Casa Piedra Road where a historic artesian well still flows today into a water storage tank. This then overflows across the road onto Plata Ranch in two diversions, supplying water for two year-round ponds on the ranch. This abundance of water is what sets this ranch apart. Acreage 173.1 Acres Description Plata Ranch is very accessible with more than a mile of frontage on paved Casa Piedra Road on the east, as well as a mile of the creek bank of Cottonwood-lined Alamito Creek to the west. There is a restored compound with new underground electrical service and a new 100 gal/minute well. -
