Part of my Geologic Structures series, this sand painting portrays a cross-section of one of the world's scenic and geological wonders: the Grand Canyon. The Colorado River has excavated a ravine which is more than a mile deep. Geologically the Grand Canyon is interesting because it contains rocks spanning 2.5 billion years of Earth History. Size: 8x10" (25 cm) rectangle with a 2" (5 cm) thick cradle. The sand painting wraps around the sides to show a geologic cross-section along each edge. The painting is strung with a wire and is ready to hang. The sand is glued to the board in multiple layers and then sprayed with an acrylic fixative sealant. Collected from around the world, the sand is un-dyed and unaltered from its natural state. The white sands are from the deep ocean and from Anna Maria Island, and Clearwater, FL. The black includes sands collected from Lake Michigan; Piha, NZ; Oregon; and from Waipipi Beach, NZ. The blue-gray sands are a mixture that includes sands from Anna Maria Island; Sea Isle City, NJ; Topsail Beach, NC; Fort Orange, Brazil; and Nelson, NZ. There is also a small amount of ground lapis lazuli (a natural mineral/rock). The green gray sand comes from a volcanic ash in the Mojave Desert which is also where the pink originates. The purple in the basement "granite" is garnet sand from Baja California. There is also granite sand from Quebec, quartz sand from Anna Maria Island, FL; and micaceous sand from Graves Mt., GA. The gray and white sand of the basement rocks comes from the base of a gneiss-granite in Tennessee. Yellow sand comes from Colorado and Nevada. Coral and orange sands come from all over the western U.S.: Moab, UT; Valley of Fire, NV; an aeolian sand near Arches NP and southern Kansas. Red sand comes from just outside of the Grand Canyon NP, AZ; the Gypsum Hills, KS; Colorado; and Utah. I create custom pieces of favorite geologic cross-sections and maps.
