Stein's Pillar area, central Oregon / Aaron C. Waters -- Seismic reflection studies of buried channels off the Columbia River / Joseph W. Berg, Jr., John M. King, and Paul R. Carlson.
The 26-mile stretch of shore extending from Florence to Yachats is one of the most rugged and scenic parts of the Oregon Coast. Along most of this part of the coast the shore is bounded by basalt bedrock of varied types. Through differential erosion of the basalt, the many landforms,...
The purpose of this paper is to give a brief description of the volcano, and to report progress in the detailed mapping and petrologic study of its caldera. The increasing use of the Paulina and East Lake areas for recreation and nature study, and widespread interest in the geology aroused...
The purpose of this study of the Lyons flora is to determine the age and paleoecology of the flora through the examination and identification of the fossil plant species of the flora. The plant fossils comprising the Lyons flora were collected from a locality in the upper Thomas Creek area,...
Seismically active areas exist within Oregon. The seismic history of Oregon is too short to be used as an accurate predictor of earthquake size, number, and distribution. Continual monitoring of earthquakes by seismograph stations during the next several decades should provide a more accurate estimate of the seismicity of Oregon....
Let us travel the 65-mile length of the Columbia River Gorge for a closer look at the rock formations and geology of the area. We will supplement our observations with information from the literature on the geology of the Gorge and try to put together a picture of how the...
This study is concerned with the post-Ice Age (Holocene) dunes in the coast segment between Coos Bay on the south and Sea Lion Point on the north. This is the longest strip of dunes along the Oregon coast and extends for a distance of about 55 miles. It is divided...
This report presents a summary of the principal geologic and physiographic features of the upper part of the Snake River Canyon between Oregon and Idaho. The area discussed extends from Farewell Bend near Huntington, Oregon downriver to Granite Creek 6 miles below Hells Canyon Dam, a distance of 94 miles....
