Metate / Rock

(0.41 miles, easy walk) This trail begins immediately east of Rock Camp Station on Highway 173. The trail leads to bedrock mortars used by the Serrano Indians to grind acorns and to make flour. The Serrano came to this area each spring because of the plentiful acorn crop and the mild weather. Bedrock mortars were formed by the grinding action of mono and pestle stones. It was much easier to use these large bedrock slabs rather than carry a mortar stone with them, but they also did that in areas where such stones did not exist. A stone monument was placed on the site by the Lake Arrowhead Woman’s Club to designate the historical importance of this encampment to the Serrano Indians.
