LIVING ON THE EDGE: RETHINKING PUEBLO PERIOD: (AD 700 – AD 1225) INDIGENOUS SETTLEMENT PATTERNS WITHIN GRAND CANYON NATIONAL PARK, NORTHERN ARIZONAMink, Philip B., II 01 January 2015 (has links)
This dissertation challenges traditional interpretations that indigenous groups who settled the Grand Canyon during the Pueblo Period (AD 700 -1225) relied heavily on maize to meet their subsistence needs. Instead they are viewed as dynamic ecosystem engineers who employed fire and natural plant succession to engage in a wild plant subsistence strategy that was supplemented to varying degrees by maize. By examining the relationship between archaeological sites and the natural environment throughout the Canyon, new settlement pattern models were developed. These models attempt to account for the spatial distribution of Virgin people, as represented by Virgin Gray Ware ceramics, Kayenta as represented by Tusayan Gray Ware ceramics, and the Cohonina as represented by San Francisco Mountain Gray Ware ceramics, through an examination of the relationships of sites to various aspects of the natural environment (biotic communities, soils, physical geography, and hydrology).
Inferences constructed from the results of geographic information system analyses of the Park’s legacy site data, indicate that Virgin groups were the first to arrive at the Canyon, around AD 700 and leaving around AD 1200. They practiced a split subsistence strategy, which included seasonal movements between maize agricultural areas in the western Inner Canyon and wild resource production areas in the pinyon-juniper forests on the western North Rim plateaus. The Kayenta occupied the North Rim, South Rim and Inner Canyon, throughout the entire Pueblo Period. Their subsistence system relied heavily on wild resource production on both rims supplemented by low-level maize agriculture practiced seasonally on the wide deltas in the eastern Inner Canyon. The Cohonina were the last to arrive and the first to leave, as they occupied the Canyon for about 300 years from AD 800–1100. They were the most prolific maize farmers, practicing it in the Inner Canyon near the mouth of Havasu Creek, but still seasonally exploiting wild resource on the western South Rim.
Based on my interpretations, use of the Canyon from AD 700-1225, is viewed as a dynamic interplay between indigenous groups and their environment. As they settled into the Canyon and managed the diverse ecology to meet their subsistence needs.

Implications of Learning Outcomes of In-Person and Virtual Field-Based Geoscience Instruction at Grand Canyon National ParkJanuary 2018 (has links)
abstract: Education through field exploration is fundamental in geoscience. But not all students enjoy equal access to field-based learning because of time, cost, distance, ability, and safety constraints. At the same time, technological advances afford ever more immersive, rich, and student-centered virtual field experiences. Virtual field trips may be the only practical options for most students to explore pedagogically rich but inaccessible places. A mixed-methods research project was conducted on an introductory and an advanced geology class to explore the implications of learning outcomes of in-person and virtual field-based instruction at Grand Canyon National Park. The study incorporated the Great Unconformity in the Grand Canyon, a 1.2 billion year break in the rock record; the Trail of Time, an interpretive walking timeline; and two immersive, interactive virtual field trips (iVFTs). The in-person field trip (ipFT) groups collectively explored the canyon and took an instructor-guided inquiry hike along the interpretive Trail of Time from rim level, while iVFT students individually explored the canyon and took a guided-inquiry virtual tour of Grand Canyon geology from river level. High-resolution 360° spherical images anchor the iVFTs and serve as a framework for programmed overlays that enable interactivity and allow the iVFT to provide feedback in response to student actions. Students in both modalities received pre- and post-trip Positive and Negative Affect Schedules (PANAS). The iVFT students recorded pre- to post-trip increases in positive affect (PA) scores and decreases in negative (NA) affect scores, representing an affective state conducive to learning. Pre- to post-trip mean scores on concept sketches used to assess visualization and geological knowledge increased for both classes and modalities. However, the iVFT pre- to post-trip increases were three times greater (statistically significant) than the ipFT gains. Both iVFT and ipFT students scored 92-98% on guided-inquiry worksheets completed during the trips, signifying both met learning outcomes. Virtual field trips do not trump traditional in-person field work, but they can meet and/or exceed similar learning objectives and may replace an inaccessible or impractical in-person field trip. / Dissertation/Thesis / Masters Thesis Geological Sciences 2018

"To Drink from Places": Uncovering a Rich Way of Life Near the Grand Canyon's North RimRich, Melinda Snow 01 May 2010 (has links)
The chapters of this thesis focus on the history and stories of the people who built and traveled down the highways--Highway 89A, Highway 89, and Highway 67--that branch out from the junction in front of Jacob Lake Inn, the Bowman/Rich family's 87-year-old lodge. The family's role in building roads, supporting and encouraging the growing tourist industry in Kanab and the North Rim of the Grand Canyon, and the converging effects of these choices have created the unique family culture and contributed to the history of the Grand Canyon region over time. Ultimately this thesis is about relationships, about the connections, influences, and choices of individuals, businesses, and government organizations that have created the myriad levels of local and national memory and unique distinctions between the tourist industry on the North and South Rims of the Grand Canyon that have framed my family's lifestyle at the junction to the National Park and surrounding scenic areas.

Chemical and Biological Problems in the Grand Canyon05 May 1973 (has links)
A survey of chemical and bacteriological water quality in the Grand Canyon was undertaken to assess possible health hazards to river travelers. The water quality of the main Colorado River channel is relatively stable with only slight increases in ionic concentration and bacteriological load with respect to distance from Lee Ferry and time over the summer season. The tributary streams show extreme temporal variability in chemical water quality and bacteriological contamination as a result of the summer rain and flood patterns in the tributary canyons. These side streams pose a definite health hazard to unwary river travelers. More extensive sampling is called for to determine the sources of this contamination and to protect the quality of the Grand Canyon experience.

Attitudes of Faculty Members Toward the Integration of Faith and Discipline at Selected Southern Baptist Colleges and UniversitiesCooper, Monte Vaughan 12 1900 (has links)
The attitudes toward the integration of faith and discipline of full-time faculty members at five selected Southern Baptist colleges and universities which are members of the Christian College Coalition were explored for this study. The integration of faith and discipline is a concept unique to Southern Baptist higher education. Arthur Walker, Jr., of the Education Commission of the Southern Baptist Convention defines the concept as referring to the mission of the institution, the personal faith of faculty members, and the professional involvement and interaction of faculty members with their students, regardless of disciplines. Since little information exists on faculty attitudes toward this concept, data were collected through a survey instrument on three dimensions of integration: professorial integration in the classroom, professorial integration in and out of the classroom, and institutional integration of faith and discipline.

An Investigation of Colorado River Trips: A User StudyBoster, Mark A., Gum, Russell L. 06 May 1972 (has links)
From the Proceedings of the 1972 Meetings of the Arizona Section - American Water Resources Assn. and the Hydrology Section - Arizona Academy of Science - May 5-6, 1972, Prescott, Arizona / Increased useer intensity of the Colorado River through Grand Canyon National Park and Monument required the national park service and the Colorado River outfitters association to adopt new policies to improve the quality of river trips and to protect the river. This study was undertaken to gain a greater awareness and understanding of visitor expectations, perceptions, interactions, satisfactions and dissatisfactions by analysis of response to a questionnaire mailed to a random sample of 2,622 past river runners from which a 65 percent return was received. Analysis of individual question tabulation and multivariate data-cluster analysis were performed. Users found crowding or user density to be at least tolerable. The largest group of runners were average in wilderness or other activities, and low relative to less strenuous activities. A large group of runners had relatively little experience in the wilderness. A large group of runners enjoyed the trip, desired more regulations, and were moderate about taking more trips. A large group rated the trip as a wilderness adventure which provided the opportunity to 'get away'. Cluster analysis is shown to be a useful tool of policy-making institutions.

SPEED AND RESOLUTION IN THE AGE OF TECHNOLOGICAL REPRODUCIBILITYTAYLOR, SHAWN 01 January 2015 (has links)
The rate of acceleration of the biologic and synthetic world has for a while now, been in the process of exponentially speeding up, maxing out servers and landfills, merging with each other, destroying each other. The last prehistoric relics on Earth are absorbing the same oxygen, carbon dioxide and electronic waves in our biosphere as us. A degraded .jpeg enlarged to full screen on a Samsung 4K UHD HU8550 Series Smart TV - 85” Class (84.5” diag.). Within this composite ecology, the ancient limestone of the grand canyon competes with the iMax movie of itself, the production of Mac pros, a YouTube clip from Jurassic park, and the super bowl halftime show. A search engines assistance with biographic memory helps our bodies survive new atmospheres and weigh the gravities that exist around the versions of an objects materiality. Communication has moved from our vocal chords, to swipes and taps of our thumbs on a screen that predicts the weather, accesses the hidden, invisible, and withdrawn information from the objects around us, and still ducks up what we are trying to say. This txt was written on a tablet returned to stock settings and embedded with content to mine the experience in which mediated technology creates, communicates and obscures new forms of language. Life in a new event horizon — a dimensional dualism that finds us competing for genetic and mimetic survival — we are now functioning as different types of humans.
