Archaeological investigations at the Cooper's Ferry site in Western Idaho have recovered cultural remains dating to 16,000 years ago, suggesting the oldest human occupation recorded in North America. However, many archaeologists have argued the initial peopling of North America occurred no earlier than the opening of an ice-free corridor between...
Subduction zone earthquake and tsunami hazards affect tens of millions worldwide and the recurrence of these disasters can be evaluated with paleoseismic techniques, because earthquake cycles (and their supercycles) typically span many millennia. In these three chapters, I discuss a suite of analyses I use to evaluate the sedimentary record...

The purpose of this investigation was to test two hypotheses.
The first hypothesis interprets allochthonous rocks in the southern
Pinyon Range to lie on the Devonian Nevada Group. The second
hypothesis interprets allochthonous rocks to lie on the Mississippian
Dale Canyon Formation. Evidence presented here supports the second
hypothesis.

AN ABSTRACT OF THE THESIS OF
Robert Vincent Visconti for the
Paleozoic dolomites, limestones, and detrital clastic rocks
were mapped in the Bellevue Peak 15 minute quadrangle in the
southern Mahogany Hills, Nevada. Sedimentary rock units in this
area represent shallow-shelf eastern assemblage deposits.
Shallow-shelf carbonates characterized deposition from at
least Ordovician through Late Devonian time, when clastics derived
from the...
