About 60,000 years ago, a glacier flowing down an earthquake slip fault cut the U-shaped Upper Kern Canyon. Look southward along the Upper Kern Canyon and you can see how the glacier carved out the canyon, giving it rounded shoulders. In the Lower Kern Canyon, below Lake Isabella where the glacier didn’t flow, the shoulders of the canyon are sharp and V-shaped.
