Description
This fault has been called various names, Threemile Fault, Threemile Creek Fault, and Three Mile Creek Fault. S. Weller et al. (1920) called it the Threemile Creek Fault and described it as extending about 3.5 miles (5.5 km) east-northeast from the west half of Section 25, T12S, R7E, to the west half of Section 16, T12S, R8E. The Threemile Creek Fault connects with the Pell Fault on the west and the Big Creek Fault on the east. The throw is down to the north and decreases westward. Defining and naming of the Threemile Creek Fault was quite arbitrary among the many intersecting and branching, mostly unnamed faults in this area.
