...F. S HUDSON Abstract The main channel of the middle Eocene Yuba River is known from its mouth, a short distance east of the western edge of the Sierra Nevada, to the present range crest, immediately northwest of Donner Pass. Abrupt changes of gradient between variously directed reaches...

.... This paper deals with a part of the uplifted zone extending from Donner Pass 10miles S. 15°E. to Squaw Peak. Here are two areas of maximum uplift caused by folding and faulting of the east limbs of the folds. The faults with greatest throw dip east at high angles, but notable movements occurred on west...

... of western Nevada had an average elevation of 2000–2500 feet. Two major components of late Cenozoic diastrophism are recognized in the Sierra Nevada. Faulting accounted for an average maximum displacement of 3500 feet in this section of the range, and regional warping ranged from 1800 feet at Donner Pass...

... and folded during a larger magnitude extensional episode that established the modern Sierran structural and topographic boundary in this area. The boundary is really a transition zone with a western edge along the Donner Pass, California, fault zone, which is farther west than previously placed. Both...

Lincoln across Donner Pass to Castle Peak, a distance of 6 miles. Following is a summary of the results of a recent study...

From the base of the Donner Lake terrace riser, along strike to the northwest, the trace of the fault is obscured for ∼400 m where it passes through a former industrial...

The present investigation was undertaken to have an understanding of the sub-recent sea level changes that affected the Kerala coast. The shell...

Such enclave swarms are relatively common in Sierran granitic plutons...
