    Amazing capture! I guess this is sand stone?

  • Thanks so much for compliments Ann.

    This arch is Water eroded White Tank Granite.
    Jointing created lines of weakness in the massive granite pluton. Water dissolved the rock surface and seeped into small cracks where it froze and expanded causing the small cracks to get larger. By chance, the result of the erosion created the arch.
