While conducting a study of the fault's capability of supporting
Isabella Dams, Treaser (1948) recorded in-depth analysis of the fault's basement rocks. His method of understanding the geology of the fault included surface study, drilling and trenching; using this approach, he was able to discern the

The Kern Canyon fault, according to the early study of Webb, is made up of 90 percent of granodiorite (a phaneritic-textured intrusive igneous rock similar to granite) and although densely covered by soils and brush, Webb discovered traces of sheared breccias and mylonites in specific zones along the

Professor Robert W. Webb of the
University of Chicago was the first to research the fault in 1936; He found a lava flow (Pliocene age) that covered the northern end of the fault trace where the Little Kern and Kern River coincided. Without any evidence of deformation affecting the hardened lava and

In 2007, Professor
Elisabeth Nadin (University of Alaska Fairbanks) discovered that while mapping the faults within the Southern Sierra Nevada, there had been several accounts of activity along the Kern Canyon Fault well into the Quaternary Era. Her research continued into 2010, which explicitly
109:
The Kern Canyon Fault Zone is a north-striking feature that harbored pre-Quaternary crustal deformation such as right-lateral strike slip and east-down normal displacement. These episodes caused bedrock displacement along the fault line, allowing the fault itself to dip steeply. It extends from

mention that this was where the Kern Canyon Fault (which shares these same rock specimens) first emerged and had drifted away from due to the constant activity within the batholith. Nadin exhumed the shear zone and recovered that it extended from the northern end of
Harrison Pass, CA to the
118:
The late-Quaternary active Kern Canyon Fault extends the ~150 km (99) miles from Walker Basin past
Harrison Pass. Its existence exploits both the Proto-Kern and Kern Canyon Fault Zones' weaknesses, resulting in ruptures along the zones over the past 15 thousand years.
79:
Due to the continued activity of the fault as well as its extension, the Kern Canyon Fault is sub-divided into three different zones; The proto-Kern Canyon Fault Zone, the Kern Canyon Fault Zone, and the late
Quaternary active Kern Canyon Fault.
