The age assigned to the Kinney Brick Quarry (early-middle Virgilian) has long been based more on its inferred lithostratigraphic position than on biostratigraphic indicators at the quarry. We have developed three datasets —-stratigraphic position, fusulinids and conodonts— that in- dicate the Kinney Brick Quarry is older, of middle Missourian (Kasimovian) age.

  • A Proposed Low Distortion Projection for the City of Las Cruces and Dona Ana County Scott Farnham, PE, PS City Surveyor, City of Las Cruces NM October 2020
    A Proposed Low Distortion Projection for the City of Las Cruces and Dona Ana County Scott Farnham, PE, PS City Surveyor, City of Las Cruces NM October 2020 Introduction As part of the ongoing modernization of the U.S. National Spatial Reference System (NSRS), the National Geodetic Survey (NGS) will replace our horizontal and vertical datums (NAD83 and NAVD88) with new geometric datums assigned in the North American Terrestrial Reference Frame of 2022 (NATRF2022). The City of Las Cruces / Dona Ana County and the City of Albuquerque / Bernalillo County submitted proposals to NGS to incorporate Low Distortion Projections (LDP) as part of the New Mexico State Plane Coordinate Systems. Approval by NGS was obtained on June 17, 2019 for the proposed systems (see approval notice). Design of the LDP is the responsibility of the submitting agencies and must be submitted to NGS on or prior to March 31, 2021. Mark Marrujo1 with NMDOT is submitting final LDP design forms to NGS for the State of New Mexico. The City of Las Cruces (City) is designing a new Low Distortion Projection for Public Works Department, Engineering and Architecture projects to NGS criteria. To meet NGS LDP minimum size and shape criterion, the LDP area extends to Dona Ana County (County) boundary lines. This report presents design analysis and conclusions of the proposed City / County local NGS LDP system for stakeholders’ review prior to NGS final design submittal. NGS NM SPCS2022 Zones and Stakeholder Organizations NGS is designing new State Plane Coordinate Systems (SPCS2022) for New Mexico. The default SPCS2022 designs for the State are a statewide single zone and the three State Plane Zones: West, Central, and East.

  • Cultural Resources Overview Desert Peaks Complex of the Organ Mountains – Desert Peaks National Monument Doña Ana County, New Mexico
    Cultural Resources Overview Desert Peaks Complex of the Organ Mountains – Desert Peaks National Monument Doña Ana County, New Mexico Myles R. Miller, Lawrence L. Loendorf, Tim Graves, Mark Sechrist, Mark Willis, and Margaret Berrier Report submitted to the Wilderness Society Sacred Sites Research, Inc. July 18, 2017 Public Version This version of the Cultural Resources overview is intended for public distribution. Sensitive information on site locations, including maps and geographic coordinates, has been removed in accordance with State and Federal antiquities regulations. Executive Summary Since the passage of the National Historic Preservation Act (NHPA) in 1966, at least 50 cultural resource surveys or reviews have been conducted within the boundaries of the Desert Peaks Complex. These surveys were conducted under Sections 106 and 110 of the NHPA. More recently, local avocational archaeologists and supporters of the Organ Monument-Desert Peaks National Monument have recorded several significant rock art sites along Broad and Valles canyons. A review of site records on file at the New Mexico Historic Preservation Division and consultations with regional archaeologists compiled information on over 160 prehistoric and historic archaeological sites in the Desert Peaks Complex. Hundreds of additional sites have yet to be discovered and recorded throughout the complex. The known sites represent over 13,000 years of prehistory and history, from the first New World hunters who gazed at the nighttime stars to modern astronomers who studied the same stars while peering through telescopes on Magdalena Peak. Prehistoric sites in the complex include ancient hunting and gathering sites, earth oven pits where agave and yucca were baked for food and fermented mescal, pithouse and pueblo villages occupied by early farmers of the Southwest, quarry sites where materials for stone tools were obtained, and caves and shrines used for rituals and ceremonies.

  • Seismic Investigation of the Yavapai-Mazatzal Transition Zone and the Jemez Lineament in Northeastern New Mexico
    Seismic Investigation of the Yavapai-Mazatzal Transition Zone and the Jemez Lineament in Northeastern New Mexico Maria Beatrice Magnani and Alan Levander Department of Earth Science, Rice University, Houston, Texas Kate C. Miller and Tefera Eshete Department of Geological Sciences, University of Texas at El Paso, El Paso, Texas Karl E. Karlstrom Department of Earth and Planetary Sciences, University of New Mexico, Albuquerque, New Mexico A new seismic reflection profile of the Precambrian lithosphere under the Jemez Lineament (JL) (northeastern New Mexico, USA) shows impressive reflectivity throughout the crust. The upper crust is characterized by a 2 km thick undeformed Paleozoic and Mesozoic sedimen- tary sequence above the Precambrian basement. At a depth of 5–8 km, undulating reflec- tions image a Proterozoic nappe cropping out in the nearby Rincon Range. To the south the upper crust is seismically transparent except for south dipping reflections at 2–10 km depth. The middle-lower crust, from 10–45 km depth, shows oppositely dipping reflections that converge in the deep crust (35–37 km) roughly at the center of the profile. To the north the reflectivity dips southward at 25° to a depth of 33 km before fading in the lower crust. In the southern part of the profile a crustal-scale duplex structure extends horizontally for more than 60 km. We interpret the oppositely dipping reflections as the elements of a doubly ver- gent suture zone that resulted from the accretion of the Mazatzal island arc to the southern margin of the Yavapai proto-craton at ~1.65–1.68 Ga.

Three spatter cones, known as the Sisters, form a distinctive skyline west of Albuquerque, New Mexico. These small volcanoes are part of the Albuquerque volcanic field and occur in the Volcanoes area of Petroglyph National Monument. The volcanic field was active about 156,000 years ago. NPS photograph by Chanteil Walter (Petroglyph National Monument). THIS PAGE Photograph of the West Mesa escarpment along the Rinconada Canyon Trail. Erosion of the Santa Fe Group sediments that underlie a basaltic cap rock has caused large blocks of rock to tumble down the eastern escarpment of the mesa.

  • User Notes: Las Cruces, New Mexico, National Wetlands Inventory
    USER NOTES : LAS CRUCES, NEW MEXICO, NATIONAL WETLANDS INVENTORY MAP Map Preparation The wetland classifications that appear on the Las Cruces NWI Base Map are in accordance with Cowardin et al .(1977) . The delineations were produced through stereoscope interpretation of 1 :110,000-scale color infrared aerial photographs taken in February, 1971, and 1 :80,000-scale bladk-and-white-aerial photographs taken in March, 1977 . The delineations were enlarged using a zoom transferscope to overlays of 1 :24,000-scale and 1 :62,500-scale . These overlays were then transferred to 1 :100,000-scale to produce the Base Map . Aerial photographs were unavailable for the western portion of the Las Cruces area 1 :62,500-scale map, the western and southern portion of the Afton area 1 :62,500-scale map, and the eastern portions of the White Sands NW, Davies Tank, Newman NW, and Newman SW area 1 :24,000-scale maps . These areas are therefore without wetland designations on the Las Cruces NWI Base Map . Extensive field checks of the delineated wetlands of the Las Cruces NWI Base Map were conducted in June, 1981 to determine the accuracy of the aerial photointerpretation and to provide qualifying descriptions of mapped wetland designations . The user of the map is cautioned that, due to the limitation of mapping primarily through aerial photointerpretation, a small percentage of wetlands may have gone unidentified . Changes in the landscape could have occurred since the time of photography, therefore some discrepancies between the map and current field conditions may exist . Any discrepancies that are encountered in the use of this map should be brought to the attention of Warren Hagenbuck, Regional Wetlands Coordinator, U .

  • Kornze Testimony Re S. 3049 Organ Mountains-Desert Peaks 9-22-16
    Statement of Neil Kornze Director U.S. Department of the Interior, Bureau of Land Management Senate Energy and Natural Resources Committee S. 3049, Organ Mountains-Desert Peaks Conservation Act September 22, 2016 Thank you for inviting the Bureau of Land Management (BLM) to testify on S. 3049, the Organ Mountains-Desert Peaks Conservation Act. The BLM supports S. 3049, which designates eight new wilderness areas and includes direction for future management on additional public lands in Doña Ana County, New Mexico. We would like the opportunity to work further with the sponsors and Subcommittee on certain aspects of the bill that we believe would facilitate implementation and improve the manageability of the areas that would be designated by S. 3049. Background Doña Ana County is many things – the county with the second highest population in New Mexico; home to Las Cruces, one of the fastest growing cities in the country; and a land of amazing beauty. Towering mountain ranges, dramatic deserts, and fertile valleys characterize this corner of the Land of Enchantment. The Organ Mountains, east of the city of Las Cruces, dominate the landscape. Characterized by steep, angular, barren rock outcroppings, the Organ Mountains rise to nearly 9,000 feet in elevation and extend for 20 miles, running generally north and south. This high-desert landscape within the Chihuahua Desert contains a multitude of biological zones – mixed desert shrubs and grasslands in the lowlands ascending to pinon and juniper woodlands, and finally to ponderosa pines at the highest elevations. Consequently, the area is home to a high diversity of animal life, including peregrine falcons and other raptors, as well as mountain lions and other mammals.
