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.

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.

Relationship Of

Documentation of the location, age and relationship of surface trace of the Teton fault zone to other geologic features is a prerequisite to a full understanding of seismic hazards associated with the fault. The University of Utah's mapping py David Sussong during the summer of 1987 documented the central portion of the fault trace. However, the northern and southern ends of the fault zone still required detailed mapping. Determination of the character of the fault in the areas south of Phillips Canyon and north of Webb Canyon can help to evaluate how movement on the fault would effect these areas, i.e., better evaluation of the relative seismic risk. Unfortunately, the extreme fire situation (the Huck fire started at the location of mapping) and the excessive time demands of the surveying reduced the amount of field mapping that we had planned for detailed geologic mapping. John Byrd, however, was able to do reconnaissance mapping in the Steamboat Mountain and Lizard Point area. In this area there is good evidence for the existence of several faults that are most likely splays of the Teton fault, that cross Jackson Lake and extend northward on the east side of the valley. Additional mapping is planned in this area next year.

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.

Topographic Relief

The Teton fault is a major, range-front normal fault that bounds the east side of the ~70 km-long Teton Range, located in northwestern Wyoming. It is an integral component of the 1,300 km-long Intermountain Seismic Belt, an active zone of intraplate seismicity that extends from southern Utah, northward through western Wyoming, eastern Idaho and western Montana. Geologically the Teton fault has evolved in the last 7 to 9 million years accumulating 6 to 9 km of displacement, concomitant with the development of the Basin-Range extensional tectonics in western Wyoming. In the past 5 to 8 million years, the nearby Yellowstone hotspot has likely influenced the activity of the fault including the timing and amount of slip on the fault. Quaternary scarps of the Teton fault extend for ~55 km, north-south along the east side of the Teton Range and provide excellent exposures of the Teton fault. The Teton fault is the primary structure responsible for producing more than 2,100 m (7,000 ft) of vertical topographic relief of the range front and is the single most important factor contribution to the spectacular topography and scenery of the Teton Range - hence to the essence of the Grand Teton National Park.

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 study was initiated in order to determine the population status of bighorn sheep (Ovis canadensis) in the Teton Range. Intensive field studies were initiated in the summer of 1978 and will be continued during the winter of 1978-79 in order to delineate the distribution of sheep and to relate this distribution to habitat factors which affect seasonal distributions. Additionally, information on the history of bighorn sheep has been sought through interviews of longtime residents of the several valleys surrounding the Teton Range.

Melanism (black fur coloration) in the yellow-bellied marmot, Marmota flaviventris, is encountered uniquely in the Teton Range in northwest Wyoming. This study is designed to investigate whether the occurrence of melanism is associated with reduced predation due to high human activity. Because overuse by humans can particularly stress the environment, the implications of this project are especially significant for Grand Teton National Park where efforts are directed to minimizing human impact. In addition, an estimation technique to calculate the likelihood that the melanistic allele is dominant is developed.

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.
