Abstract
The general geology of the north Santiam River section of the Oregon Cascades:
The district discussed in this paper is located in North-western Oregon, about fifty-miles south of the Columbia River. The section investigated extends eastward from the Willamette River a few miles south of Salem to the Cascade Range summit between Mount Jefferson and Olallie Butte. It follows the North Santiam River, which is near the 44° 45’ parallel. The area includes portions of the Salem, Lebanon, Stayton, Mill City and Mt. Jefferson quadrangles of the Topographic Atlas of the United States and part of a fifteen minute quadrangle west of the Mill City sheet which was mapped by the author.
The stratigraphy and paleontology of the Salem Hills, Oregon:
The part of the Salem Hills considered in this paper lies south and east of the Willamette River south of Salem, Oregon. The area is in the middle of the Willamette Valley, midway between Eugene and Portland, and occupies the southeastern part of the Salem quadrangle of the Topographic Atlas of the United States.
