   According to engineering geologist Peter Anderson, the rock that forms El Toro was originally created far under the ocean in volcanic eruptions more than 100 million years ago. Moving at a gradual rate over the span of eons, the Pacific Plate transported the rock northeast from somewhere just south of the equator to where the South Valley is now.
   
   The bulk mass of El Toro is altered volcanic rock, Anderson said. But what gives the landmark mountain its characteristic peak has nothing to do with volcanism. During its long transit from the Pacific, the volcanic rock became mixed with limestone of the same era. After the extensive period of mountain building which formed the Santa Cruz Mountains - a process which is still going on - erosion has taken its toll on El Toro. The limestone at the top of the mountain is more resistant to erosion than the altered volcanic rock layers below. Thus the limestone situated at the summit of El Toro serves much like a "cap," Anderson said, shielding the underlying rock from erosion.
   
   In a million or so years, the limestone cap will be eroded by natural elements such as wind and rain, thus exposing the underlying volcanic rock.

   Longtime gem smith Bill Tyrol and local geologist Peter Anderson recently came across a large sample of unusually high quality poppy jasper that they felt belonged in Morgan Hill.

   Peter Anderson, geologist for Dr. & Mrs. Cohen, said he had completed a geologic evaluation of the landslide and its effect on the Cohens' property. He said he was in agreement with all of the geology results discussed by Mr. Wallace and felt he had done a fine job in characterizing the different options for repair. One of his key concerns was what had caused the slide to begin with. Three factors were involved: 1) the slope of the stratification; 2) very heavy rains; and 3) the steep slope initially cut for the construction of Cervantes Road. He had also looked at the possibility of sliding below the road and agreed that the potential for that happening was very low. He said the repair options presented were very thorough for the deep-seated slide area, but that there was an additional failure just off of the Cohens' property line. If the slide debris was swept away, he felt there was potential for this area to migrate.
