Last night I took some photos of the sands sent by Kathy Obersinner. There are really nice sands, with lots of minerals of different colors. The samples are maily from Alaska and Hawaii but also from California, Florida, Oregon, Illinois, Chicago, Mississippi, Washington. Additionally, several sands from New Zealand, Mexico, Canada and Bahamas. I already took photos of about 25 sands so please check the Sand Photomicrography section for new photos.
