Sands have been magnified about 20 times (see below) to reveal their composition and beauty.  We all know sand from walking on the beach, but when viewed under magnification, surprises await. As sand composition varies from site to site, each tells its own geologic story of the region or the local marine biodiversity.

Magnification depends on both the manner in which the image was photographed and how it is displayed. Note the scale bar at the bottom left of the sand images for a sense of magnigication.
