Detailed Description

Another picture of greensand, this is the same sample as the last one, but one that was wetted down ... what follows is the rest of the post from the previous picture of greensand....greensand dug from my backyard, which at one point was on the ocean floor...and at a point in the future will return to that state. Our local greensand is composed of rounded marine sand, glauconite (the greensstuff), and geothite (small brown/black particles). One of the strawbale walls of my bathroom is plastered using using local brown clay and greensand to achieve a lovely olive green wall...a bit sandy since the rounded sand particles have no "bite." Photography Information: Canon Mark II 5D, Zerene Stacker, Stackshot Sled, 65mm Canon MP-E 1-5X macro lens, Twin Macro Flash in Styrofoam Cooler, F5.0, ISO 100, Shutter Speed 200. USGSBIML Photoshopping Technique: Note that we now have added using the burn tool at 50% opacity set to shadows to clean up the halos that bleed into the black background from "hot" color sections of the picture.
