Honeycomb weathering, also known as honeycombs, honeycombed sandstone, is a form of cavernous weathering that consists of regular, tightly adjoining, and commonly patterned cavities that are developed in weathered bedrock; are less than 2 cm (0.79 in) in size; and resemble a honeycombed structure. Honeycombs also been called alveoli, lacework, stonelace, fretting, or miniature tafoni weathering.[1][2] The size at which honeycombs are differentiated from tafoni varies greatly in the scientific literature and lacks an official consensus.[3]
