Stratigraphy, Petrology, Diagenesis, Paleontology, and Depositional Environments of the Harrisburg Member of the Kaibab Formation in Northern Arizona and Southern Utah
<p>The Kaibab Formation has two members, the Fossil Mountain Member below and the Harrisburg Member above. They were deposited in shallow-marine shelf to restricted coastal settings. Stratigraphically above are the Rock Canyon Conglomerate and the Moenkopi Formation; consisting of the Timpoweap and …

Timing of erosional episodes in the Marble Canyon and Vermilion Cliffs region from apatite (U-Th)/He thermochronology
… of the Vermilion Cliffs) to 2420 m (top of the Kaibab uplift). I find that samples from these different elevations record different components of a multi-stage cooling history for this region. Samples along the Colorado River in Marble Canyon show that rocks resided above 110 °C until 30 to 40 …

The Sequence Stratigraphic Context of Mixed Basin Margin Evaporites in the Harrisburg Member of the Permian Kaibab Formation, Northern Arizona and Southern Utah
<p>The Kaibab Formation is a mixed carbonate system including evaporites and siliciclastics deposited on a westward dipping epeiric carbonate ramp during the middle Permian in northern Arizona, southern Utah, and eastern Nevada. It consists of the Fossil Mountain Member deposited in open-marine …

Correlation of earthquakes with seismogenic faults along the Northern Arizona Seismic Belt, southwestern margin of the Colorado Plateau.
… distinct geomorphic lineaments within the West Kaibab fault system, which to the point has minimal documented evidence of late Neogene movement. Recognition of recent seismicity along the West Kaibab fault system is consistent with the hypothesis that Basin and Range extensional faulting is …

Applications of Remote Sensing and GIS to Modeling Fire for Vegetative Restoration in Northern Arizona
… to predict prescribed fire behavior on the Kaibab-Paiute Reservation. ArcGIS was used to create a database incorporating all variables into a common spatial reference system and format for the FARSITE model. ArcGIS Spatial Analyst was then used to select optimal burn sites for simulation. …

Biogeography of Montane Mammals on the Colorado Plateau and Adjacent Regions
… subclade with populations from the Kaibab plateau, and are closely related to the Northwest clade. Past approaches to studying montane mammal communities utilizing theory based on island biogeography have overemphasized area and isolation as the only forces structuring insular …

Predicting Northern Goshawk Dynamics Using an Individual-based Spatial Model
… based on demographic data from studies in the Kaibab National Forest, and depicted a declining trend. This outcome was not expected, as the observed population is assumed to be stable. Nest surveys in areas not related to proposed timber sales, and local estimates for adult survival and …

The 2006 Warm Fire: effects on habitat and prey species of the northern goshawk
… pine and mixed-conifer forest on the North Kaibab Ranger District in northern Arizona in late June and early July 2006. Forest habitat metrics such as live tree and snag densities, cone production, canopy and ground cover estimates were collected from 2007-2010 on 60 0.5km transects to …

Forest structure in unharvested old-growth: understanding the influence of soils on variability of long-term tree dynamics and fire history
… of mixed conifer and spruce fir forests on the Kaibab Plateau, located on the North Rim of the Grand Canyon. My methodology targeted the largest trees and identified the oldest trees in the mixed conifer plots 97% of the time (in all but one plot). While a complete census of all trees would …
