Personal Log 

We are anchored in East Bight and I continue to work on lesson plans.  It is a beautiful clear day with many great photo opportunities.  I take advantage of the expertise of Intern Umeko Foster, who gives me a crash course in using the sextant.  I reluctantly admit to owning a sextant for many years and not using it to navigate. Umeko is an excellent teacher and for the first time I am able successfully move the sun to the correct position on the horizon! As a bonus, Umeko demonstrates the correct way to read degrees and minutes.  After dinner, Able Seaman Leslie Abramson drives the liberty boat to and from the beach so crew members can enjoy a little r and r. I ask Leslie to take me on a cruise to a nearby outcrop of rocks with many geologic structures.

Geologic structures are everywhere in this outcrop.  Save this picture to your desktop and enlarge it.  How many faults, dikes, sills, and folds do see?
