Baja California II

PTYS 594A: 
Planetary Geology Field Practicum

This semester the University of Arizona Planetary Geology field trip went to Baja California, stopping at sites on the east (Sea of Cortez) and west (Pacific) coasts to view shoreline processes, and also at a site in the interior which may show landslides triggered by the KT impact.

Day 4:  Cañon San Fernando to Punta San Jose

On the dirt road from San Tomas to Punta San Jose we ran into a few dozen motorcycles on a practice run for next week's Baja 1000 race, and pulled over to let them go by.

Ammonites at Punta San Jose

We arrived at Punta San Jose at relatively low tide, and went down to the beach to search for ammonite fossils eroding out of the cliffs.
