Description: Table Rock is located on the northeast peninsula of Kelley’s Island. Kelleys Island is in fact a mass of solid limestone rock, lifted about twelve feet out of the Lake Erie, and rising in some points to an elevation of 40 or 50 feet above the level of the lake. Geologically, the island consists of successive strata of Columbus limestone with as many as 60 layers which vary in thickness from 2 to 8 inches and full of marine fossils. The eastern shores of the island have mostly been worn smooth from a westbound glacier, producing gentle shores full of rocky beaches. Western facing shores are more sharp and jagged, with erosion caused from the waves of lake. Table Rock is an excellent example, having been separated from the mainland from wave erosion. Standing on a single pedestal, it has undermined to such an extent that is almost ready to topple over. Columbus limestone can be found in a north-south line from Kelleys Island in Lake Erie to south of Columbus and many quarries are, or have been, actively removing this high-calcium limestone for use in production of cement, rip-rap, driveway gravel and road base, agricultural lime, and other uses. The unit was formed in a clear, shallow, tropical sea that covered the state. Fossils of marine animals are abundant in the Columbus Limestone. View on Ohio Memory.

Description: Marblehead Lighthouse in Marblehead, Ohio, United States, is the oldest lighthouse in continuous operation on the United States side of the Great Lakes. It has guided sailors safely along the rocky shores of Marblehead Peninsula since 1822, and is an active aid to navigation. In 1819, the fifteenth U. S. Congress recognized the need for navigational aides along the Great Lakes, and set aside $5,000 for construction of a light tower at the entrance to Sandusky Bay. Contractor William Kelly built the 50 foot (15 m) tower of native limestone on the tip of the Marblehead Peninsula. The base of the tower is 25 feet (7.6 m) in diameter, with walls five feet (1.5 m) thick. It narrows to 12 feet (4 m) at the top with two-foot (0.6 m) thick walls. The turn of the century ushered in new technology as well as structural changes including the addition of another 15 feet (4.6 m) to the tower’s height. A clock-like mechanism was installed to rotate the lantern, creating the appearance of a brilliant flash of light every 10 seconds. This system required that the lighthouse keeper crank the weights every three hours through the night to keep the lantern turning. An improved Fresnel lens with prism surfaces created an even more brilliant beacon. An electric light finally replaced the kerosene lantern in 1923, dramatically increasing the intensity of the signal. During World War II, the lighthouse became strategically important for national defense. The last civilian lighthouse keeper resigned, and the United States Coast Guard assumed responsibility for the beacon in 1946. The beacon was automated in 1958. With its original finish tattered by time and harsh weather, the exterior of the lighthouse tower was given a fresh coat of new stucco the same year. It was added to the National Register of Historic Places in 1969. The Ohio Department of Natural Resources has maintained the property surrounding the lighthouse since 1972 and accepted ownership of the Marblehead Lighthouse tower in May 1998. The U.S. Coast Guard continues to operate and maintain the lighthouse beacon. Today’s 300 mm lens projects a green signal that flashes every six seconds and is visible for 11 nautical miles (20 km). The distinctive green distinguishes the lighthouse signal from white lights coming from air beacons. In 2001-2002 the state renovated the tower and keeper's house at a cost of $500,000. In 2004 the Fresnel lens was returned to the light station from the Marblehead Coast Guard Station, where it was previously on display. The Ottawa County Historical Society owns the original 1-story fieldstone keeper's house (3 miles (5 km) from the light on OH 163 in Marblehead. The lighthouse is now part of the 9 acre Marblehead Lighthouse State Park. The park features picnic tables and offers views of Lake Erie, Sandusky Bay, Kelleys Island and South Bass Island. The Marblehead Lighthouse Historical Society operates the Marblehead Lighthouse Museum in the old keeper's house View on Ohio Memory.

Description: This photograph shows, what is most likely, gravel from the quarry on Kelley's Island, being loaded from a railcar onto a cargo barge. The Kelley Island Lime & Transport Company, founded in 1896, and which was once the largest producer of limestone and lime products in the world, closed the early 1960s. Numerous ruins of these operations and quarries now dot the island. The East Quarry closed in 1940 and is now a state park. Kelley’s Island, originally known as Island Number 6 and later Cunningham Island, was renamed in 1840 for brothers Datus and Irad Kelley, who were largely responsible for cultivating the island's quarrying, logging and winemaking industries. In 1975, 23 acres on the island's southern shore were designated a historic district, the "Kelleys Island South Shore District," and added to the National Register of Historic Places. In 1988, the district was renamed to the "Kelleys Island Historic District" and expanded to include the entire island. View on Ohio Memory.
