The listing, Hidden Valley Secrets postcard has ended.
Old Postcard reads: Hidden Valley Secrets. There are many rock formations in the park that indicate a history of chaotic upheaval. Great masses of irregular sizes and shapes thrust their ghostly shadows in the sand. Over eons of time they are ravaged by wind, blasts of sand, extreme cold and heat. This granite formation can be found near the picnic grounds in Hidden Valley.. Photo by Buster L Wright.
