Directions: Examine the Drakes Bay, California map. Locate Point Reyes, a landmass bounded to the west by the Pacific Ocean, on the south by Drakes Bay, and to the east by the San Andreas Fault.
Question 1. Which area is more resistant to wave erosion (less likely to break down) : Point Reyes (at the end/point) or Point Reyes Beach (where the beach is)? What observations can you make on the map to support your answers?
Question 2. Find Drakes Estero in the central portion of the map. How might Drakes Estero (Spanish: estuary) have formed? Rising sea levels that flooded a river valley.
Question 3. Do you think this is a coastline of emergence or submergence? Explain
Question 4. What is the pattern of longshore drift in Drakes Bay? How can you tell?
Question 5. If a groin was constructed from Limantour Spit at the "n" in Limantour, then on what side of the groin would sand accumulate (east or west)? Why?
