This fine overhanging ledge furnished what appears to be an ideal house
site, although apparently it was never used as such. Perhaps the women
would gather here in the shade on hot days to chat and grind their corn
or make pottery. Undoubtedly, Indian children have played in its cool
protection.
The ledges of this type were used by prehistoric Indians because they
afforded good watertight roofs for their homes which could be completed
by construction of walls only in front and on the sides. The recesses
were formed by a process called differential weathering or exfoliation.
Moisture seeps into the cracks behind the surface of the softer layers
of limestone. When the water freezes it expands, cracking off thin
layers of rock.
