Detailed Description

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.
