Historie
Spearfish Canyon's geological history dates back approximately 600 million years to the Precambrian era when the area was submerged under a sea.
Over the Paleocene to Oligocene epochs, from about 60 to 30 million years ago, erosion shaped the canyon as softer rock was worn away.
The scenic byway follows a former railroad grade that was abandoned after devastating floods in 1933.
Over time, the canyon has become a protected natural area within the Black Hills National Forest, preserving its unique geological and ecological features.
