I had to do something different with Brevig Mission, because technically the sample wasn't sand. Geologists identify sand grains as falling between 1/16 of a mm to 2 mm. Anything larger is a pebble. We are dealing with pebbles here! All of the pebbles are igneous, and they are very varied. What I tried to do was give a cross section of the different pebbles that make up this very unusual sample. The top image was taken at ZERO MAGNITUDE , but I included a scale bar because the photograph had to be taken at a much higher elevation to include the samples. All of the other images were taken at 1X MAGNIFICATION . Enjoy!! Thanks Pam for a great sample from this very remote site.
