Actually, we didn’t meet her diving…….we went to a lecture she gave at Ocean Enterprises about the various theories of human migration from Asia and the underwater archeological evidence, which might be present locally in La Jolla, at various depths, for human habitation along the coastline within the past 40,000 years.
Dr. Norrie Robbins, PhD of the Dept. Geological Sciences at San Diego State University presented us with some fascinating data/theories about what archeological evidence might lie beneath the surface at various depths right off the coast of San Diego, to wit:
“This project I am trying to start, Deep Underwater Archaeology, needs people who dive to approx. 160 ft (180-140 is probably the range).
The Calif. history we are trying to discover is the history of people from 20,000-40,000 years ago. Onshore, archaeologists have a clean record from 14,000 years to the present. Archaeologists also have a nice record of villages along the 8,000-year-ago shoreline (now under 25 ft of water). Deep divers are needed to understand when people first arrived here and where they landed and lived.

Here’s the data set, just in case people want to start looking around:
8,000 years ago now under 25 ft of water
20,000 390 ft of water (edge of continental shelf exposed)
30,000 150 ft of water
40,000 160 ft of water
60,000 50 ft of water
Local divers know about the mortars which lay in 10-15 ft. of water locally off of the Marine Room, depending on the tides, evidence of Indian habitation here 4-8,000 years ago.
Now, she says, there may be even more archeological evidence at deeper depths, for those willing to explore them.
How cool is that?
