This promontory's sandstone formations provide habitat for communities of algae, bacteria, and fungi. These communities have colonized about 80 percent of the rock formation.
Similarities between surface conditions on Antarctica and Mars lead some scientists to study these organisms as potential analogues of Martian life.
