Part of my Geologic Structures series, this sand painting portrays the gentle folding in the bedrock geology the upper Midwest. Associated with the rise and subsequent erosion of the Appalachian Mountains to the east, the crust gently sagged as erosional products filled up the regional basin features. 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 base 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, red and green pebbly sands come from Orepuki "Gemstone Beach," NZ. The gray angular sand comes from Belfast, ME and includes broken mussel shells. Yellow pebbly sand comes from Colorado and the Hocking Hills, OH. Yellow orange sand is from the Isle of Wight, UK. The purple pebbly sand is garnet gneiss sand from Baja California. Red and orange sands come from The Sahara Desert; Utah; Arizona; the Hocking Hills, OH; the Gypsum Hills, KS; Colorado; and from near Uluru, Australia. The off-white and pink sand comes from the Bahamas. The blue-gray sands are a mixture that includes sands from Anna Maria Island; Andalusia, AL; Sea Isle City, NJ; Topsail Beach, NC; Fort Orange, Brazil; and Nelson, NZ. Medium brown sand comes from Old Rope Mill Park in Cartersville, GA, and light brown sands come from the Coromandel Peninsula, NZ; Corolla, NC; and Melbourne Beach, FL. I create custom pieces of favorite geologic cross-sections and maps. Please contact me if you would like to discuss this option!
