SAMPLE #1

PAPAKOLEA BEACH, PUU MAHANA BEACH , HAWAII 18.54N, 155.40W

Sorry about the quality of the Zero Magnification image, but the amount of sand sent to me was very small. This is the most southern point in the United States. FLASH!! I just received a second sample! Sample #2 had enough to cover the bottom of the Petri Dish!

 

The link is to a blog from Northern Virginia Community College that shows great images of the area, as well as explaining a little about the geology from the location. The images are incredible! There is also a spectacular avalanche video of green sand from the beach.
