| Description |
At Hance Creek, Basalt Dikes shoot through the Hakatai Shale, a geologic wonder easily seen from the end of the New Hance Trail. NPS Photo by: Carl Bowman Hakatai Shale Thickness: 445-985 feet This colorful formation contains layers of red sandstones, red shales, and blue to purple shales. As the sea level dropped, the environment slowly changed from a shallow sea to coastal mud flats. Mudcracks, raindrop impressions, and cross-beds are found in this layer. |
