We welcome this further discussion of our results on the age of the Great Gallery rock art in the Canyonlands of Utah. The comment by Simon and Reed (1) focuses on just one of the three components of our study (2), which is presented in greater technical detail in ref. 3 and is surely our best-constrained and least-surprising result: the dating of a rock-fall that removed some of the art and thus provides a minimum age. Simon and Reed (1) point out that the Great Gallery panel is not pristine and relate the sordid human history of visitation and possible …
Home Range Characteristics Of Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper
Home Range Characteristics Of Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper
Canyonlands Research Bibliography
We studied home-range characteristics of adult Mexican Spotted Owls (Slyix occidentalis lucida) in southern Utah. Twenty-eight adult owls were radio-tracked using a ground-based telemetry system during 1991-95. Five males arid eight females molted tail feathers and dropped transmitters within 4 wk. We estimated cumulative home ranges for 15 Spotted Owls (12 males, 3 females). The mean estimate of cumulative home-range size was not statistically different between the minimum convex polygon and adaptive kernel (AK) 95% isopleth. Both estimators yielded relatively high SD, and male and fernale range sizes varied widely. For 12 owls tracked during both the breeding and nonbreeding …

Seismic Reflection Study Of Upheaval Dome, Canyonlands National Park, Utah, Z. Kanbur, J. N. Louie, S. Chavez-Perez, G. Plank, D. Morey
Canyonlands Research Bibliography
The origin of Upheaval Dome, in Canyonlands National Park of southeastern Utah, has been a topic of controversy among geologists and planetary scientists. The structure has long been thought to have been created by salt diapirism from the underlying Paradox Formation. Recent studies have suggested that impact could have formed the dome. To test the various hypotheses, we acquired, processed, and interpreted seismic reflection data within and adjacent to the structure. Both conventionally stacked and prestack-migrated images show <100 m relief in the Paradox Formation, contrary to salt diapirism hypotheses. Further, we have identified features within the images typical of impact structures, such as listric normal faults having displacements toward the center of the dome. Deformation occurs in two depth ranges, with the faulting that created the central uplift appearing only above the Hermosa Formation, in the upper 800 m of the structure. The images also suggest limited fracturing of the Hermosa and salt flow in the Paradox Formation, perhaps due to gravitational relaxation of the crater form. Our image of a nearly flat top of the Paradox salt strongly favors an impact origin for Upheaval Dome.
First-Year Movements By Juvenile Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper
First-Year Movements By Juvenile Mexican Spotted Owls In The Canyonlands Of Utah, D. W. Willey, C. Van Riper
Canyonlands Research Bibliography
We studied first-year movements of Mexican Spotted Owls (Strix occidentalis lucida) during natal dispersal in canyonlands of southern Utah. Thirty-one juvenile Mexican Spotted Owls were captured and radiotracked during 1992-95 to examine behavior and conduct experiments related to the onset of natal dispersal. Juvenile Spotted Owls dispersed from their nest areas during September to October each year, with 85% leaving in September. The onset of movements was sudden and juveniles dispersed in varied directions. The median distance from nest area to last observed location was 25.7 km (range = 1.7-92.3 km). Three of 26 juveniles tracked (11%) were alive after …

Water Resources Management Plan Arches National Park And Canyonlands National Park, United States Department Of The Interior National Park Service
Water Resources Management Plan Arches National Park And Canyonlands National Park, United States Department Of The Interior National Park Service
All U.S. Government Documents (Utah Regional Depository)
This Water Resources Management Plan describes the water resources of Arches and Canyonlands National Parks and the issues affecting them. This plan provides detailed descriptions of the hydrologic environment in both parks, discussion of management issues developed in two scoping sessions, and management directives in the form of project statements. Typically, a Water Resources Management Plan is preceded by a scoping meeting held at the park. In this case, the Southeast Utah Group of parks (Southeast Utah Group), which includes Arches National Park, Canyonlands National Park, and Natural Bridges National Monument, held two scoping meetings. The first scoping session, held …
Holocene Archeology Near Squaw Butte, Canyonlands National Park, Utah
Holocene Archeology Near Squaw Butte, Canyonlands National Park, Utah
All U.S. Government Documents (Utah Regional Depository)
This document is the final technical report of cultural resources investigations in the Needles District of Canyonlands National Park, southeastern Utah. These investigations were part of the multiyear Canyonlands Archeological Project. Inventory of 878 acres in the Squaw Butte Area revealed 80 sites which were occupied by Archaic people during all phases of the Archaic period, aborigines of unknown cultural affiliation during the Early Formative period, Mesa Verde Anasazi during Pueblo III or late Pueblo II-III, and the Navajo during historic or modern times. Paleoindians may have also been in the general area, if not the actual project area. Limited …
Cultural Resource Inventory And Testing In The Salt Creek Pocket And Devils Lane Areas, Needles District, Canyonlands National Park, Utah, United States Department Of The Interior National Park Service
Cultural Resource Inventory And Testing In The Salt Creek Pocket And Devils Lane Areas, Needles District, Canyonlands National Park, Utah, United States Department Of The Interior National Park Service
All U.S. Government Documents (Utah Regional Depository)
This document is the final technical report on the first phase of a multiyear archeological program conducted in Canyonlands National Park. Some of the purposes of this project are to gather information for upgrading the park's interpretive program, increase the scientific understanding of Canyonlands' prehistory, and prepare a research design to guide future investigations. Archeological inventory of 4500 acres in the Needles District revealed a previously undocumented Archaic occupation and showed that Formative peoples using the area were primarily the Mesa Verde Anasazi, not the Fremont and Anasazi as previously thought. The data also indicate that prehistoric peoples used the …
Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Soil Properties In Relation To Cryptogamic Groundcover In Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Canyonlands Research Bibliography
A comparative study was made of the soils of a virgin grassland and an adjacent grazed area in Canyonlands National Park. Soils from the virgin site were finer textured than those of the grazed area, and the surface 5 cm contains a significantly lower amount of calcium. In addition, the surface 5 cm of the virgin site contains significantly greater amounts of phosphorus, potassium, and organic matter. Subsurface soils in the two parks are less dissimilar. Cryptogams on the virgin grassland appear to have an important influence on chemical characteristics of the surface 5 cm of soil. The difference in …

Environment And Communiy Organization In Grasslands Of Canyonlands National Park, Edgar F. Kleiner, K. T. Harper
Canyonlands Research Bibliography
Sixty uniformly distributed stands in adjacent areas, 40 in Virginia Park (virgin) and 20 in Chesler Park (grazed), were analyzed. Cryptogamic and vascular species were recorded; cover was analyzed by the point sampling method, and frequency by means of 25 quadrats (each 0.125 m^2) per stand. The prevalent species (26 in Virginia, 23 in Chesler) were selected on the basis of a constancy-times-frequency index. Interspecific association patterns were determined by means of simple procedures based on quadrat frequency values for each species in the individual stands. Major environmental variables were recorded at each stand, and soil samples from four depths …
