| Figure 18. Photograph of the area of Stop 3, looking northwest. The dark patches in the center of the picture are exposures of “Breccia no. 1.” Mafic rock dominates the area immediately surrounding the breccia to the line of grassy knolls behind and uphill from the breccia. Running along the crest of the line of knolls is a northeast-trending felsic dike. The large ridge in the background is Monterey Mountain. Grazing cows provide scale. |
