Description: Five photographs document Nelson Ledges, a group of sandstone rock formations in Portage County. A sixth photograph shows the lodge built for visitors. Nelson Ledges is one of the few areas of northeastern Ohio where sandstone cliffs were not covered by receding glaciers. Nelson Ledges was purchased by the state of Ohio in 1940 and became part of Nelson-Kennedy Ledges State Park in 1949. The photographs measure 8" x 10" (20.32 x 25.4 cm). View on Ohio Memory.

Description: Flint is Ohio's official gemstone and Flint Ridge flint is renowned for its color and beauty. These samples shown here include one stone with crystals measuring 14" x 11" x 6" (35.6 x 27.9 x 15.2cm) and two polished stones measuring 2" x 3" x 2" (5.1 x 7.6 x 5.1cm) each. Flint is silicon dioxide (SiO2)--the same chemical formula as the quartz crystals that are visible on the first image. Small specks of other minerals included in the crystal give it its varied appearance. In prehistoric times, the flint was used by American Indians for tools including knives and spear points; today, the polished stone is valued in jewelry making. The most famous deposit of flint in Ohio is an area in eastern Licking and western Muskingum Counties known as Flint Ridge. Flint Ridge Flint became Ohio's official gemstone in 1965.

Description: This 8 x 10-inch (20.32 x 25.4 cm) photograph document a geologic formation commonly known as Indian Head Rock. The rock is located near Old Man's Cave in Hocking Hills State Park. Old Man's Cave was named for Richard Rowe, a hermit who moved to the Ohio Valley in 1796 and lived in the cave. Early settlers named the site Cedar Falls, mistaking the hemlock trees that surround the falls for cedars. In 1924, the state of Ohio purchased 146 acres in the Hocking Hills that became Hocking Hills State Park in 1949. In 1972, the park added a dining lodge and cabins. Hocking Hills State Park is known for its geologic features of blackhand sandstone, including Old Man's Cave, Cedar Falls, and Rock House. View on Ohio Memory.

Description: This 2.75" x 2.75" (6.99 x 6.99 cm) photograph of the Cleveland Quarries in Amherst, Ohio, was taken in the 1960s. Amherst is known for its large formation of high-quality sandstone, which runs roughly from Berea, Ohio to Amherst. The area has been labeled the "Sandstone Center of the World." John Baldwin, founder of what is now Baldwin-Wallace College, is credited with discovering the sandstone formation in 1842. Several quarries were already operating in the area. The Cleveland Stone Company bought out several of the smaller ventures in July 1886. The Ohio Quarries, owned by John R. Walsh, organized in 1903 in competition with Cleveland Stone Company. In 1929, Cleveland Stone purchased the Ohio Quarries and became the Cleveland Quarries Company. View on Ohio Memory.

Description: Five photographs document the glacial grooves found on Kelleys Island as they looked in the 1930s or 1940s. The photographs measure 6" x 3.5" (15.24 x 8.09 cm). The glacial grooves on the north side of Kelleys Island are the largest easily accessible such grooves in the world. They were scoured into solid limestone bedrock about 18,000 years ago by the great ice sheet that covered part of North America. Remaining today is a trough that measures 400-feet long, 35-feet wide, and up to 10-feet deep. The ice, probably hundreds of feet thick, flowed from the north in what is now the Lake Erie basin. The Devonian limestone containing the grooves contains marine fossils that are 350 to 400 million years old. Many other grooves were quarried away during the nineteenth and twentieth centuries.
