Integrative Natural History of Southern Illinois, Part 1: Sandstone Cliff Face with Tafoni Texture | Ferne Clyffe State Park, Illinois, USA
A view of the park's Round Bluff. Here the Pounds Sandstone Member of the Pennsylvanian-subperiod (Upper Carboniferous) Caseyville Sandstone shows the scooped-out tafoni texture that sometimes develops in weathered sandstone.
The otherworldly pale-blue color of the rock face is largely the result of the crustose-lichen community inhabiting it. The cliff is also home to various nonvascular-plant (liverwort and moss) species.
