Eight in-service teachers, one pre-service education student, three observers from other universities, and two instructors from the University of Nebraska-Lincoln engaged in an inquiry-based geology field course from June 13 to 28, 2015 through Wyoming, South Dakota, and Nebraska. This commnity of learners spent three days working in the Grand Teton National Park area. Geological features and history present in Grand Teton National Park are an important part of the course curriculum. Large-scale extensional features of the Teton Range and Jackson Hole, and the glacial geomorphology and related climate changes of this area are some of the unique features examined here.

Eight in-service teachers and two instructors engaged in an inquiry-based geology field course from June 14 to 29, 2014 through Wyoming, South Dakota, and Nebraska. This team of learners spent three days in mid-June working in the Grand Teton National Park area. The UW-NPS facilities provide an excellent opportunity for participants to discover the natural history of the Teton Range, as well as close-out a few projects while sitting in a real chair, at a real table, a welcome change from our usual campground setting.

During summer 2010, the University of Wyoming American Studies Program conducted an intensive cultural landscape survey and historical analysis of the Elk Ranch in Grand Teton National Park. Led by Research Scientist Mary Humstone, students documented the ranch landscape and remaining buildings. They conducted research in local archives to uncover the history of the ranch and determine its significance in the history of Jackson Hole and Grand Teton National Park. The team determined that the property is eligible for the National Register of Historic Places, with significance in agriculture and conservation.

Under the auspices of the U. S. Geological Survey and the University of Washington, detailed investigations of Miocene vertebrates and sediments in Jackson Hole, Wyoming commenced in 1979. Principal objectives of this research include: 1. Documenting the occurrence of mid-Tertiary mammals from Jackson Hole. Although fossils have been reported from Miocene rocks in the region (Love, 1956; Sutton and Black, 1972), existing collections are small. 2. Biostratigraphic correlation of isolated vertebrate localities throughout the northern Rocky Mountains with the superimposed localities in and near Grand Teton National Park. Such correlation will help determine whether regional or local tectonic events caused downwarping of Jackson Hole and uplift of the Teton Range. 3. Clarifying geographic variation of some small mammals through long periods of geologic time by comparison of West Coast (Rensberger, 1971, 1973;· Martin, 1979), Great Plains (Macdonald, 1963, 1970; Galbreath, 1953; Wilson, 1960), and the newly collected Jackson Hole faunas. This report summarizes accomplishments of the 1980 field season. Approximately one more season of field work and an ensuing year of data analysis are required before a final report will be available.

This is a progress report on the research of the University of Utah project: "Earthquake Hazards of The Grand Teton National Park Emphasizing The Teton Fault", to date, 31 December, 1989. The research objectives during 1989 focussed on: 1) excavation of a trench across the Teton fault to determine the age and amount of displacement associated with prehistoric ground breaking earthquakes; 2) collection of paleomagnetic samples of Huckleberry Ridge tuff along an E-W transect across the northern end of the Teton range to assess deformation associated with the Teton fault; 3) mapping and surveying of two study areas along the fault to evaluate the geomorphic expression of the fault; 4) surveying a detailed topographic and gravity profile across the valley from String Lake to the Snake River to evaluate deformation of the valley floor and to help constrain modeling of the subsurface fault geometry, 5) continuing the study of expected fault motion of the Teton fault based on our previous results, 6) mapping of the northern extent of the Teton fault zone, and 7) assisting the NPS with interpretations and use of our data for management and interpretational purposes.

Fifteen permanent bench marks were established east and south of the existing 22 km-long line of 50 bench marks across the Teton normal fault in Grand Teton National Park to compare height changes of Jackson Hole relative to the Teton Range on the west and Shadow Mountain on the east. The new bench marks, together with three other agency bench marks and three temporary bench marks, constitute a 7. 8 km-long extension to the existing line tied to the old line at bench mark GT01. The new bench marks were precisely leveled between 30 August and 5 September 1994. Misclosure of the double-run survey was 0.86 mm, thus the precision of the total survey is 1 part in 10 million. If the misclosure is simply spread equally among the (n-1) bench marks, then the probable error associated with the relative height of a single bench mark is effectively zero.

The Snake River plains and foothill areas of Jackson Hole have been grazed by domestic livestock since settlement of the area. Wildlife populations, including elk (Cervus elaphus), buffalo (Bison bison), mule deer (Odocoileus hemionus), and antelope (Antilocapra americana) have historically used the area. Moose (Alces alces) are currently relatively abundant. Currently, livestock continue to use part of the area contained in Grand Teton National Park either as a concession or due to authorization by Park enabling legislation. Large grazing wildlife also inhabit the Park area. Park managers need information concerning the effects of grazing by large ungulates on vegetation resources, to achieve desired plant community goals by effectively managing grazing.

Recent earthquake activity in the Jackson Hole area, particularly the 2010 Gros Ventre sequence, has focused on possible regional ground deformation that may be related to the earthquakes (Farrell et al., 2010). The University of Utah has an established network of field GPS benchmarks that was last surveyed in 2003 and has now been resurveyed in 2010 (Figure 1). The campaign GPS measurements supplement the permanent regional GPS network and provide detailed information on temporal and spatial deformation in and around Grand Teton National Park.

Harrison R. Crandall (or "Hank" as he preferred; Fig. 1) is best known for his paintings and photographs of the Teton Range, and ranch scenes of Jackson Hole, Wyoming. However, Hank 's multi-faceted life, which spanned the period from 1887-1970, was far more interesting and important than is generally recognized. He was the first artist and commercial photographer to operate a studio in the Jackson Hole area, but he was also a valley homesteader, an important supporter and patron in the establishment of the Grand Teton National Park, and a pioneer concessionaire of the National Park art and souvenirs before the advent of mass tourism. Hank's natural artistic talent was accompanied by a complex personality - a mixture of the spirited individualism required of a mountain adventureer and dry-land homesteader, a loving and dedicated family man who promoted shared labor and leisure, and an environmentally attuned visionary who helped many to interpret the meaning of the Grand Teton National Park experience.

A study of coyote (Canis latrans) habitat use and mortality in Grand Teton National Park and the suburban-agricultural land surrounding Jackson, WY was conducted between September 1999 and August 2000. This research focused on the influence of human development, habitat type, topography, and simulated wolf presence on coyote habitat use and on coyote mortality patterns in undeveloped and suburban-agricultural land. The overall goal of this project was to provide baseline information on the coyote population in Jackson Hole that can be used in the future to determine what, if any, impact wolves and human developments may have on coyotes. There were a total of fifteen radio-collared coyotes in the suburban-agricultural area and fourteen radio collared coyotes in Grand Teton National Park and adjacent areas in the National Elk Refuge and Bridger-Teton National Forest. Marked coyotes were tracked weekly using short interval telemetry relocations and triangulation to determine habitat use patterns. During the winter, track transects were skied weekly and coyote trails were backtracked and mapped using hand held GPS units to determine fine scale habitat use patterns. Coyote mortality was determined via telemetry and direct observation. Preliminary data analyses suggest that coyotes use mainly sagebrush-grasslands or forest-shrub-grass edge areas and avoid forest interior areas. Coyotes frequently use trails and roads in the undeveloped area when moving long distances. Preliminary analysis also indicates that roads and trails are used in a greater proportion than their abundance on the landscape. Coyotes were frequently observed using riparian corridors to move between open meadows in the suburban-agricultural area. There is some evidence that suggests coyotes selectively travel fences and irrigation ditches for long distances in agricultural areas. The movement data also suggests that coyotes avoid developed areas during the day and travel in these developed areas at night. The data on coyote locations suggests some avoidance of wolf urine scent grids in the undeveloped area, but not in the developed area. Coyote mortality was primarily human caused, and coyotes that were male, transient, and lived in the suburban-agricultural area were the most commonly killed animals.

The Snake River plains and foothill areas of Jackson Hole have been grazed by domestic livestock since settlement of the area. Wildlife populations, including elk, mule deer, and antelope have historically used and continue to use the area. Moose are currently relatively abundant and a small herd of bison have been introduced. Currently, livestock use part of the area contained in Grand Teton National Park either as a concession or due to authorization by Park enabling legislation. Park managers need information concerning the effects of grazing by large ungulates on vegetation resources to assist in effectively managing grazing to service forage needs and achieve desired plant community goals.
