Little Finand, Gold Butte National Monument, Nevada
Wind carved Navajo sandstone with tafoni rock formations. Tafoni occur in various settings and rocks, as in sandstone. Here, they are small cavities in this sandstone presumably generated by salt crystallization pressure, where by the crystal occupies a slightly increased volume, resulting in fracture of the rock with subsequent erosion. The initial nucleus for crystallization can be formed by organism living in the sandstone.
