The Coyote Hills are located about 46 kilometers north-northwest
of Lakeview, Oregon, within the Basin and Range physiographic province.
These hills represent a complex volcanic center of bimodal
calc-alkaline igneous activity.
The oldest rocks recorded in the Tertiary succession are horn-blende-
bearing andesite and aphanitic basalt flows, laharic breccias,
conglomerates,...

We present 36 new ⁴⁰Ar-³⁹Ar incremental heating age determinations from the Caribbean Large
Igneous Province (CLIP) providing evidence for extended periods of volcanic activity and suggest a new
tectonomagmatic model for the province’s timing and construction. These new ⁴⁰Ar-³⁹Ar ages for the
Curaçao Lava Formation (CLF) and Haiti’s Dumisseau Formation...

Bridge Creek is a small stream which runs through the central Oregon high desert region. Ranching, the area's primary industry, was degrading conditions in the stream. A group of ranchers and environmentalists, working as part of the Oregon Watershed Improvement Coalition, forged an agreement on what was needed for a...

One important cool-season perennial grass seed crop grown in Oregon is fine fescue (Festuca rubra L.). Open-field burning has been used for many decades to manage pests, cycle nutrients, and stabilize yield, in fine fescue seed fields, especially as stands age. Legislative restrictions currently limit open-field burning to 6,070 hectares...
The middle to upper Eocene Tillamook Volcanics form the basement in the Rock
Creek - Rocky Point area. These tholeiitic to alkalic basalts, basaltic andesites, and
andesites were erupted as shield volcanoes seaward of the strandline ontop of an older
deep-marine mudstone unit (Yamhill Formation) and an accreted portion of...
