Description |
A oval, whole, shaped and flat grinding stone platform, also known as a metate. The object is unique due to the white color and material; it is a white leucocratic (granite) with medium grains of quartz and muscovite mica. Leucocratic granite is found in Valley Center and Fallbrook in San Diego County, CA. The metate has a central grinding surface that was formed by rotary grinding movements typically with a hand-held grinding stone, called a mano. This grinding or milling stone's ventral platform is polished for a central area that is 19.5 inches (49.5 cm) long and 10 inches (25.5 cm) wide. Construction of the stone created a smooth rectangular surface. The dorsal side of the stone is curved and sloping, uneven with speckled areas of minute biotite. There are brownish stains in several spots. Dimensions: Length - 20.708", Width - 11.259", Height - 4.094", Weight - 37 lbs. |
