  • 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.

  • Fort Davy Crockett: Browns Park National Wildlife Refuge (Colorado)
    U.S. FISH AND WILDLIFE SERVICE: REGION 6 - CULTURAL RECOURSE PROGRAM Fort Davy Crockett?: An Archaeological Mystery Browns Park National Wildlife Refuge – Northwest Colorado Summarized from: A Report on the Results of Limited Subsurface Testing at 5MF5478, a Proposed Site of Historic Fort Davy Crockett, Moffat County, Colorado Kristen D. Kent and Mona C. Charles, Department of Anthropology, Fort Lewis College, Durango, Colorado December 2004 Introduction The follow excerpts are from a 2004 report documenting archaeological testing at the possible location of Fort Davy Crocket on the Brown’s Park National Wildlife Refuge. Many studies and much research has been conducted over the years to try and determine if the remains found on a bluff overlooking the Green River on the Browns Park National Wildlife Refuge are indeed those of the Fort. This research adds additional insight into the mystery. Fort Davy Crockett In 1837 three fur trappers, Prewett Sinclair, Philip Thompson, and William Criag, formed a partnership and reportedly built Fort Davy Crockett that same year. The Fort was named after the famous Tennessee frontiersman who died at the Battle of the Alamo in Texas the previous year. Kit Carson, another famous frontiersman, trapper and scout is reported to have been employed by the owners of Fort Davy Crockett. In 1839 members of the Peoria Party on their way to Oregon reported staying at the Fort. A description of the Fort was provided in the recordings of Thomas Jefferson Farnham, leader of the Peoria Party. He described the Fort thus: The fort, as it is called, peered up in the centre, upon the winding banks of the Sheetskadee.

This is one of many related papers that were included in the 2012 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.

  • Notes on Paleocene and Lower Eocene Mammal Horizons of Northern New Mexico and Southern Colorado
    56.9(1181:78.9). Article XXXII.- NOTES ON PALEOCENE AND LOWER EOCENE MAMMAL HORIZONS OF NORTHERN NEW MEXICO AND SOUTHERN COLORADO. BY WALTER GRANGER. PLATES XCVII AND XCVIII. The purpose of the present short paper is to indicate some of the results of the Eocene exploration conducted by the writer, with the assistance of Mr. George Olsen, in the San Juan Basin in 1916. It is hoped that the fol- lowing notes may be of some aid to future Eocene collecting in this region and possibly also to detailed geologic plotting. Three separate localities were examined, viz.: the Torrejon of Angel Peak, lying south of the San Juan River; the Torrejon of the Animas Valley, between Aztec and Cedar Hill; a set of later beds in Colorado, lying north of the Denver and Rio Grande Railway, between Los Pifios and Piedra Rivers. The American Museum expedition of 1913 visited nearly all of the Paleocene localities of the San Juan Basin from which fossils had previously been obtained, made extensive collections and summarized the strati- graphic results in a paper published the following year.1 These localities are all on the south side of the San Juan River and extend in a long line from the vicinity of Ojo Alamo eastward to the Puerco River below Cuba. Exposures lying to the north near the San Juan and in the Animas Valley were known to be Paleocene but for lack of time were not examined that year. The Angel Peak Region. The exposures at Angel Peak are in the form of a gigantic crater cut out of a fairly level grass-covered plain to a depth of several hundred feet and with a diameter of three to four miles.

  • VOLCANIC INFLUENCE OVER FLUVIAL SEDIMENTATION in the CRETACEOUS Mcdermott MEMBER, ANIMAS FORMATION, SOUTHWESTERN COLORADO
    VOLCANIC INFLUENCE OVER FLUVIAL SEDIMENTATION IN THE CRETACEOUS McDERMOTT MEMBER, ANIMAS FORMATION, SOUTHWESTERN COLORADO Colleen O’Shea A Thesis Submitted to the Graduate College of Bowling Green State University in partial fulfillment of the requirements for the degree of MASTER OF SCIENCE August: 2009 Committee: James Evans, advisor Kurt Panter, co-advisor John Farver ii Abstract James Evans, advisor Volcanic processes during and after an eruption can impact adjacent fluvial systems by high influx rates of volcaniclastic sediment, drainage disruption, formation and failure of natural dams, changes in channel geometry and changes in channel pattern. Depending on the magnitude and frequency of disruptive events, the fluvial system might “recover” over a period of years or might change to some other morphology. The goal of this study is to evaluate the preservation potential of volcanic features in the fluvial environment and assess fluvial system recovery in a probable ancient analog of a fluvial-volcanic system. The McDermott Member is the lower member of the Late Cretaceous - Tertiary Animas Formation in SW Colorado. Field studies were based on a southwest-northeast transect of six measured sections near Durango, Colorado. In the field, 13 lithofacies have been identified including various types of sandstones, conglomerates, and mudrocks interbedded with lahars, mildly reworked tuff, and primary pyroclastic units. Subsequent microfacies analysis suggests the lahar lithofacies can be subdivided into three types based on clast composition and matrix color, this might indicate different volcanic sources or sequential changes in the volcanic center. In addition, microfacies analysis of the primary pyroclastic units suggests both surge and block-and-ash types are present.
