The Middle Fork John Day Basin in Northeastern Oregon is prime habitat for spring Chinook salmon and Steelhead trout. In 2008, a major tributary supporting rearing habitat, Big Boulder Creek, was restored to its historic mid-valley channel along a 1 km stretch of stream 800 m upstream of the mouth....
A technique was developed in the present study to determine
fault-plane solutions for small earthquakes. The method uses the
direction and amplitude of initial P-wave motions recorded at a
small number of seismic stations for epicentral distances less than
2000 km.
Seismic arrivals recorded on short-period seismograms were
identified as...

Late Cretaceous sedimentary marine and deltaic rocks of
Gabriola Island were mapped and studied during the summer of 1971.
Cretaceous strata constitute all the exposed outcrops on the island,
which is the northernmost of the Gulf Island chain of British Columbia.
The upper four formations of the Nanaimo Group are...

The Mount Fubilan Intrusion is part of a geologically young hypabyssal stock in the Star Mountains of Papua New Guinea. This stock was mapped as the Ok Tedi Intrusive Complex and divided into four separate bodies: the Mount Fubilan, Sydney Intrusion, Kalgoorlie, and Ningi Intrusions. Hydrothermal fluids caused alteration of...

The biodiversity of most marine communities is more or less dependent on continuous invasions from sources with greater richness. These ongoing, natural invasions have become greatly augmented by ship traffic in numerous estuaries and harbors where the native biota has been diminished or lost due to habitat destruction and pollution....

a party of men across the Sierra Nevada to the
Pacific coast of California in 1833. Previous
interpretations of the portion of the route
from Humboldt Sink, Nevada, to the San Joaquin
River, California, are not satisfactory. A

A RESEARCH PAPER
submitted to
THE DEPARTMENT OF GEOGRAPHY
OREGON STATE UNI
Acquisition of divergent-productive thinking skills by using
elementary science materials constitutes the basic idea of this experiment.
The data collected was used to determine statistically if
the materials had a significant role in inducing such skills.
The Ss were fifth-grade students obtained from two public elementary
schools in Oregon. Those...
