1680 a large section of the mountain suddenly fell in from ‘the 
undermining of the mass by the Indian miners, killing a con-

swung as sledges, fashioned with wedge-shaped edges and a 
groove for a handle. A hammer weighing over twenty pounds 
was found while I was at the Cerillos, to which the wyth was

is found growing abundantly on the hillsides—now quite well 
perserved after at least two centuries of entombment in this 
perfectly dry rock.
