These twelve crescents were found on sites in the
Black Rock Desert area in northwestern Nevada. One
or two of them might be classified as winged crescents
but most of them are good examples of lunate crescents.
They are made of various types of good quality chert.
The top center crescent is made of agate. The largest
one, in the center, measures 2 5/8 inches (6.6 cm) long.
