Hocking Hills State Park is a state park in Ohio, United States. Within the park are over 25 miles of hiking trails, rock formations, waterfalls, and recess caves.
In the southernmost reaches of Hocking Hills is Ash Cave, the largest, most impressive recess cave in the state. The horseshoe-shaped cave measures 700 feet from end to end, 100 feet deep from the rear cave wall to its front edge with the rim rising 90 feet high. The cave was named after the huge pile of ashes found under the shelter by early settlers.

Underwater rivers are formed when the fresh top water meets the exposed salty groundwater. The different density levels in the two waters causes them to layer. Undersea rivers are similar to the rivers we see on land. They have banks on either side, They carve valleys into the sea floor and follow meandering paths. These rivers were unknown until the 1980s, when sonar mapping of the seafloor began to reveal them.
Angelita in Yucatan, Mexico, looks like any ordinary swimming hole. It’s not until you dive almost 100 feet that the underwater river becomes exposed.

Multnomah Falls is located on Multnomah Creek in Oregon, US. Spanning two tiers on basalt cliffs, it is the tallest waterfall in the state of Oregon at 620 ft (189 m) in height. The falls drops in two major steps, split into an upper falls and a lower falls. The two drops are due to a zone of more easily eroded basalt at the base of the upper falls. Underground springs from Larch Mountain are the year-round source of water for the waterfall, augmented by spring runoff from the mountain’s snowpack and rainwater during the other seasons. According to legend from the Multnomah tribe (from whom the falls take their name), the waterfall was formed after a young woman sacrificed herself to the Great Spirit to save Multnomah village from a plague by jumping from the cliff. After her death, water began to flow from above the cliff, creating the waterfall. Multnomah Falls is the most visited natural recreation site in the Pacific Northwest with more than 2 million stopping by each year.

Hamilton Pool Preserve is a natural pool that was created when the dome of an underground river collapsed due to massive erosion thousands of years ago. The pool is located about 23 miles (37 km) west of Austin, Texas. The pool is surrounded by large slabs of limestone that rest by the water’s edge. Large stalactites grow from the ceiling high above. The ceiling and surrounding cliffs of the grotto are home to moss, maidenhair fern and cliff swallows. The Ashe juniper (cedar) uplands of the preserve are home to the endangered golden-cheeked warbler.

Maly Semyachik is a stratovolcano located in the eastern part of Kamchatka Peninsula, Russia. A hot, acidic crater lake fills the historically active Troitsky Crater, which formed during a large explosive eruption about 400 years ago. The water in the lake has an unusual bright turquoise color. It’s because the waters of the lake are poisonous due to the content of several types of acids and other chemical compounds.The water in the lake never freezes, even when everything is covered with a layer of ice and deep snow.

Victoria Falls is a waterfall in southern Africa on the Zambezi River at the border between Zambia and Zimbabwe. David Livingstone, the Scottish missionary and explorer, is believed to have been the first European to view Victoria Falls in 1855. Livingstone named his sighting in honour of Queen Victoria of Britain, but the indigenous Lozi language name, Mosi-oa-Tunya—”The Smoke That Thunders” continues in common usage as well. While it is neither the highest nor the widest waterfall in the world, Victoria Falls is classified as the largest, based on its combined width of 1,708 meters and height of 108 meters resulting in the world’s largest sheet of falling water. Victoria Falls is roughly twice the height of North America’s Niagara Falls and well over twice the width of its Horseshoe Falls. There are two islands on the crest of the falls that are large enough to divide the curtain of water even at full flood: Boaruka Island (or Cataract Island) near the western bank, and Livingstone Island near the middle—the point from which Livingstone first viewed the falls.
