Hastings Natural History Reservation

09 Apr, 03 AM - 09 Apr, 09 AM

Volcanic rocks (basalts) crop out in Carmel Valley at various locations, including Arrowhead Point, Rancho San Carlos, and Hastings Reserve. The age of the basalt outcrop at Arrowhead Point has been determined by radiometric dating. However, the volcanic rock outcrops at Hastings have not been dated. The Tularcitos Fault crosses Hastings Reserve and has possibly offset the Arrowhead Point volcanic rocks from the Hastings Reserve outcrops, for a distance of nearly 40km. Dating of the Hastings outcrops could help us evaluate if these are similar age rocks to those at Arrowhead Point. If the rocks are similar age, then this could be used to calculate a slip rate along the Tularcitos Fault, which is a key piece of information in evaluating seismic hazards of the Santa Lucia Range.
