A reef of mottled sandstone is exposed at low tide. 



The " Patterned sandstone " differs from the usual mottled sandstone in 



having a mottling that somewhat resembles the crystal pattern on a polished 



surface of meteoric iron. The colors are lemon-yellow, white and pink, in a 



ground of bluish-purple. It is softer than the reddish -purple sandstone.
