Scoping Report For The Glen Canyon Dam Long-Term Experimental Plan Environmental Impact Statement, U.S. Department Of The Interior, Bureau Of Reclamation

All U.S. Government Documents (Utah Regional Depository)

This report summarizes the issues raised during the initial scoping process for the Bureau of Reclamation's Long-term Experimental Plan for Glen Canyon Dam Operations and Other Management Actions Environmental Impact Statement (EIS). This report describes the initial scoping process and presents the schedule, describes the scoping meetings, summarizes comments submitted by the public, and provides an overview of the relevant issues that Reclamation anticipates will be analyzed in the EIS.

Scoping is defined by the regulations implementing the National Environmental Policy Act (NEPA) as the process whereby lead agencies solicit input from the public on what the issues and alternatives …

Paleomagnetic Dating Of Fault Slip In The Southern Rocky Mountains, Usa, And Itsimportance To An Integrated Laramide Foreland Strain Field, T. F. Wawrzyniec, Alexis K. Ault, J. W. Geissman, E. A. Erslev, S. D. Fankhauser

Geosciences Faculty Publications

The Laramide orogen of the U.S. Cordillera formed in the latest Cretaceous, and deformation lasted into the earliest Oligocene. Along and proximal to the eastern and northern margins of the Colorado Plateau, deformation associated with this event mainly took place along reactivated structures. Related tectonic models invoke some role for the plateau either as a stress guide transmitting compression to the foreland or as a freely rotating microplate. Models dominated by northward displacements of the Colorado Plateau also require covariance between timing and magnitude of dextral strike-slip deformation in the eastern domain and thrust deformation in the northern domain. Here …

Dendroarchaeology Of The Salt Lake Tabernacle, Utah, Matthew F. Bekker, David M. Heath

Wasatch Dendroclimatology Research

We examined tree rings from Douglas-fir (Pseudotsuga menziesii var. glauca (Beissn.) Franco) timbers in the Salt Lake Tabernacle, constructed from 1863–1867 in Salt Lake City, Utah. A seismic upgrade to the Tabernacle initiated in 2005 required the replacement of wooden timbers with steel beams. Our objectives were to 1) determine cutting dates for the timbers to identify logs that may have been salvaged from previous structures, and consequently would have greater historical significance, 2) identify the species and provenance of the timbers, and 3) develop a chronology that could extend or strengthen the existing tree-ring record for environmental and …
