NE, Suite 200 Box 25425 Albuquerque, New Mexico 87110 Denver, Colorado 80225 Foreword The Regional Aquifer-System Analysis Program The Regional Aquifer-System Analysis (RASA) program was started in 1978 after a congressional mandate to develop quantitative appraisals of the major ground-water systems of the United States. The RASA program represents a systematic effort to study a number of the Nation's most important aquifer systems that, in aggregate, underlie much of the country and that represent important components of the Nation's total water supply. In general, the boundaries of these studies are identified by the hydrologic extent of each system, and accordingly transcend the political subdivisions to which investigations have often arbitrarily been limited in the past. The broad objective for each study is to assemble geologic, hydrologic, and geochemical information, to analyze and develop an understanding of the system, and to develop predictive capabilities that will contribute to the effective management of the system. The use of computer simulation is an important element of the RASA studies, both to develop an understanding of the natural, undisturbed hydrologic system and any changes brought about by human activities as well as to provide a means of predicting the regional effects of future pumping or other stresses. -

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.

Coordinated drilling efforts are an important method to investigate active tectonics and magmatic processes related to faults and volcanoes. The US National Science Foundation (NSF) recently sponsored a series of workshops to define the nature of future continental drilling efforts. As part of this series, we convened a workshop to explore how continental scientific drilling can be used to better understand active tectonic and magmatic processes. The workshop, held in Park City, Utah, in May 2013, was attended by 41 investigators from seven countries. Participants were asked to define compelling scientific justifications for examining problems that can be addressed by coordinated programs of continental scientific drilling and related site investigations. They were also asked to evaluate a wide range of proposed drilling projects, based on white papers submitted prior to the workshop. Participants working on faults and fault zone processes highlighted two overarching topics with exciting po- tential for future scientific drilling research: (1) the seismic cycle and (2) the mechanics and architecture of fault zones. -

The Plate Boundary Observatory
The Plate Boundary Observatory Results of the First Workshop on Geological Research Held at Pasadena, California May 22-25, 2001 Submitted by PBO Geology Committee Douglas Burbank Ken Hudnut (PBO Steering Committee) Rick Ryerson Charles Rubin PBO Geology White Paper/Page 1 David Schwartz (Chair) Brian Wernicke (PBO Steering Committee) Steve Wesnousky Introduction The diffuse plate boundary zone of the western US and Alaska consists of hundreds of active tectonic elements that collectively accommodate large-scale relative motions between the North American, Pacific and Juan de Fuca plates (Figure 1). The major plate-bounding structures include the San Andreas transform and the Alaskan and Cascadia subduction zones, which accommodate most of the relative plate motion. Each of these features is a system of faults, each of which either fails in repeated large earthquakes or creeps aseismically. In addition to these fault systems, areally extensive structural domains within the North American plate, such as the Basin and Range province, Rio Grande rift, Rocky Mountains and interior Alaska accommodate up to 30% of the relative plate motion (Figure 1). PBO Geology White Paper/Page 2 Figure 1. Tectonic setting of the Pacific-Juan de Fuca-North America plate boundary system, showing major fault systems and locations of proposed geodetic instrumentation. Courtesy of PBO Steering committee. The life-cycle of an individual fault zone lasts on the order of 1 to 10 Myr, and the repeat times of major earthquakes (durations of the seismic cycle) are on the order of hundreds to thousands of years or more. Hence any attempt to understand tectonic systems must include observations on these time scales. -

Delayed and Rapid Deglaciation of Alpine Valleys in the Sawatch Range, Southern
Delayed and rapid deglaciation of alpine valleys in the Sawatch Range, southern Rocky Mountains, USA Joseph P. Tulenko1, William Caffee1, Avriel D. Schweinsberg1, Jason P. Briner1, Eric M. 5 Leonard2. 1. Department of Geology, University at Buffalo, Buffalo, NY 14260, USA 2. Department of Geology, Colorado College, Colorado Springs, CO 80903, USA 10 Abstract We quantify retreat rates for three alpine glaciers in the Sawatch Range of the southern Rocky Mountains following the Last Glacial Maximum using 10Be ages from ice-sculpted, valley-floor bedrock transects and statistical analysis via the BACON program in R. Glacier retreat in the Sawatch Range from at (100%) or near (~83%) Last 15 Glacial Maximum extents initiated between 16.0 and 15.6 ka and was complete by 14.2 – 13.7 ka at rates ranging between 35.6 to 6.8 m a-1. Deglaciation in the Sawatch Range commenced ~2 – 3 kyr later than the onset of rising global CO2, and prior to rising temperatures observed in the North Atlantic region at the Heinrich Stadial 1/Bølling transition. However, deglaciation in the Sawatch Range approximately aligns 20 with the timing of Great Basin pluvial lake lowering. Recent data-modeling comparison efforts highlight the influence of the large North American ice sheets on climate in the western United States, and we hypothesize that recession of the North American ice sheets may have influenced the timing and rate of deglaciation in the Sawatch Range. 1 While we cannot definitively argue for exclusively North Atlantic forcing or North 25 American ice sheet forcing, our data demonstrate the importance of regional forcing mechanisms on past climate records.
