...C. S. Ferris Abstract The eastern Owl Creek Mts. are part of a block of Precambrian and younger rocks moved upward and southward in early Eocene by a moderately high angle thrust fault. The toe of the thrust became broken by normal faulting and the part behind it became the Copper Mtn. arch. Cedar...

... no evidence of induced seismicity in this catalog. The seismicity pattern shows earthquakes occurring beneath areas of high topography in the Bighorn and Owl Creek Mountain ranges. This may indicate a preference to slip on pre‐existing weaknesses created during mountain building. The absence of earthquakes...

... of the Owl Creek Range, forming the southern margin of the Bighorn basin. An estimated 80 per cent of the detrital beds are characterized by andesitic débris; dacitic detritus predominates in most of the remainder. Most beds contain a small proportion of non-volcanic débris, and a few beds contain entirely...

... at 2.16 Ga, before rifting ( c. 2.1–2.0 Ga) and eventual reamalgamation after the Hudsonian Orogeny ( c. 1.8 Ga). U–Pb ages (TIMS on baddeleyite) from five dykes yield two groups of ages at c. 2164 and 2155 Ma. The younger group of ages defines the Rabbit Creek swarm at 2161–2152 Ma and precisely...

Mapping and paleoseismic investigation of these previously unknown scarps provide constraints on the earthquake history and seismic hazard in the northern Puget Lowland. The Kendall scarp lies along the mapped trace of the Boulder Creek fault, a south-dipping...
