Hocking Hills State Park

Hocking Hills State Park is a state park in the Hocking Hills region of Hocking County, Ohio, United States. In some areas the park adjoins the Hocking State Forest. Within the park are over of hiking trails, rock formations, waterfalls, and recess caves. The trails are open from dawn to dusk, all year round, including holidays.
The park contains seven separate hiking areas: Ash Cave, Cantwell Cliffs, Cedar Falls, Conkle's Hollow (nature preserve), Old Man's Cave, Rock House and Hemlock Bridge Trail to Whispering Cave.
History.
The name Hocking Hills
Hocking County was named after the Hockhocking River. Hockhocking, in the Delaware tongue, signifies a bottle. In Shawnee, Wea-tha-Kagh-Qua-sepe, meant bottle river. The Hockhocking River had a waterfall of nearly 20 feet located about 6 or 7 miles northwest of Lancaster. Above the falls, the creek was very narrow and straight, forming the "bottle" neck.
The Hockhocking enters the county from Good Hope Township in the northwest and then flows southwest, touches Marion Township, continues through Falls and Green Townships, and exits the county through northwestern Starr Township. The river is then in Athens County.
History: The Adena culture is believed to be one of the first inhabitants of the area of Hocking Hills 1700s - Native American Tribes of Delaware, Wyandot, and Shawnee travelled through and lived in the area 1818 - Hocking County created in Ohio 1830s - Powder mill was built 1840 - Hocking Canal was completed allowing for more settlers to travel there 1924 - After local popular hiking areas were threatened by the accessibility of more traffic, the State Forest Law was passed in 1915 allowing the state to purchase the first parcel of land in Hocking Hills around Old Man's Cave.
History of the Park
More than 330 million years ago, the Hocking Hills State Park area was relatively level and was covered by the waters of the Atlantic Ocean. For millions of years, the ocean's currents deposited immense amounts of sand and gravel. After millions of years, the ocean receded, and the sandy layers bonded with silica to form the Black Hand Sandstone that underlies the area. It formed like a sandwich, with a hard top and bottom and a soft middle layer. When the Appalachian Mountains arose, form and feature were cast upon the area and created Hocking Hills State Park.
Hocking Hills State Park was hemmed in by the ancient north-flowing Teays River to the west, and the then north-flowing Hocking to the east. The landscape remained fairly static for millions of years. Any changes were minuscule, and were slow to develop. When the Wisconsin Glacier began melting back to the north about 10,000 years ago, the landscape would undergo dramatic changes. The glacier stopped in northern Hocking County, so the area suffered indescribable flooding. The ancient Teays River was buried under tons of glacial silt, and the direction of the Hocking River was reversed.
When the glacial torrents found cracks in the hard capstone, the water poured through to flush out the soft middle layer. This left long tunnels where the gorges are today. Eventually, the weight of the tops caused them to come crashing down. The "slump rocks" in the gorges today are what's left of the hard top layer. In just a few centuries, the rushing waters of the glacier carved the soft middle layer of sandstone into the myriad dimples and wrinkles that decorate the cliffs and grottos today.
Early settlers in Muskingum County found an ancient black human handprint on a cliff that is part of this same sandstone formation. That is the same "Black Hand Sandstone" that is seen in six areas of the Hocking Hills State Park.
Hocking Honor Camp Reforestation
Hocking Hills' iconic and unusual hemlock forest of Hocking Hills was extensively established by the Civilian Conservation Corp and Division of Forestry in the 1930s. Additional planting and reforestry work took place during the 1950s by "prisoners from the Hocking Honor Camp." Inmates "worked on tree planting, cleaning plantations and pruning more established plantations.The prisoners earned five cents per hour for their labor if they had dependents, otherwise they earned half a cent per hour for their hard work." This unique model of using inmates to provide social good is striking. According to the Logan Daily News, Hocking Honor inmates "worked closely with the Hocking County area and the community, an idea that seems absurd today"
Tourist accommodations.
There are about 200 campsites in the park, most equipped with electricity. The campground is close to all of the hiking trails in the area and has flush toilets, shower houses with hot water, vending machines, a camp store, a pool, and other amenities. The area also has many cabins and hotels in this area.
In 2017, over 2 million people visited Hocking Hills. To handle the growing tourism, a summer shuttle service from downtown Logan began to lessen the overtaxing on the park's parking facilities. The Ohio Department of Natural Resources (ODNR) broke ground on a new visitors' center. The $6 million project opened in June 2019. 
Attractions.
The area is very popular with tourists and collectively is known as the Hocking Hills Region. It features many private inns, campgrounds, cabins, restaurants, and other related businesses, including a recently developed zipline. Other attractions include:
Flora
Several rare plants are known from this area, including plants that are outside their normal range. Canadian yew, bigleaf magnolia, and many others are here.
Trails
There are numerous hiking trails, including several safe for pets, located throughout the state park. Some trails in Hocking Hills State Park include: 
In popular culture.
Many of the adventures in Jeff Smith's comic book series "Bone" take place in Old Man's Cave, a place inspired by the Hocking Hills State Park, which Smith enjoyed since he was a child. The waterfalls of the park also influenced Smith's frequent use of water as a recurring visual element in "Bone", calling it "an age-old storytelling symbol".
Other public lands.
As noted, Hocking Hills State Park is embedded within the Hocking State Forest. Crane Hollow Nature Preserve, a private preserve, fills in a large part of the non-public area. On the south side, Camp Oti-Okwa, owned by Big Brothers-Big Sisters, is also a sizeable protected area. There are three state nature preserves within the Forest, but only Conkles Hollow State Nature Preserve is open to the public. Also nearby are Clear Creek Metro Park, Lake Logan State Park, and Rockbridge State Nature Preserve.
