Jan. 30- Morteros
From Blair Valley, following the dirt road south along the mountain edge, we rode our bikes to a trailhead leading towards a jumble of huge boulders. This was the site of a Kumeyaay Indian village for thousands of years, where women would grind seeds in depressions on the huge rocks. Eventually morteros or mortars were worn deep into the rocks. The abundant agave plants on the surrounding slopes would be harvested by the men and roasted in pits.
Morteros worn into the granite boulder!
Agave and Yucca were important resources for the Kumeyaay.
