Question: Lake Winnepesaukah has the oldest ride of what type, which finishes with a climactic splashdown?

full_context: Document 1: Indian Springs State Park: Indian Springs State Park is a 528-acre (2.14 km²) Georgia state park located near Jackson and Flovilla. The park is named for its several springs, which the Creek Indians used for centuries to heal the sick. The water from these springs is said to have a sulfur smell and taste. Indian Springs is thought to be the oldest state park in the nation. It was acquired from the Creek Indians by the state through the Treaty of Indian Springs (1825) and the Treaty of Washington (1826). Thereafter, Indian Springs has been operated continuously by the state as a public park, although it did not gain the title "State Park" until 1931. The area became a resort town in the 19th century. It became an official "State Forest Park" in 1927. In 1931, along with Vogel State Park, it became a founding unit of Georgia's state park system.
Document 2: History of the roller coaster: Roller coaster amusement rides have origins back to ice slides constructed in 18th-century Russia. Early technology featured sleds or wheeled carts that were sent down hills of snow reinforced by wooden supports. The technology evolved in the 19th century to feature railroad track using wheeled cars that were securely locked to the track. Newer innovations emerged in the early 20th century with side friction and underfriction technologies to allow for greater speeds and sharper turns. By the mid-to-late 20th century, these elements intensified with the introduction of steel roller coaster designs and the ability for them to invert riders.
Document 3: Lake Winnepesaukah: Lake Winnepesaukah, commonly known as Lake Winnie, is an amusement park located in Rossville, Georgia, just south of Chattanooga, Tennessee. Carl and Minette Dixon opened the park to over 5,000 guests on June 1, 1925. They named it after the Native American word "Winnepesaukah", meaning “bountiful waters” or “beautiful lake of the highlands”. The park originally featured the largest swimming pool in the southeastern United States, which debuted in 1926 and was later removed. Its Boat Chute attraction, designed by Carl Dixon, opened in 1927 and is the oldest mill chute water ride of its kind still in operation in the United States.
Document 4: Cannon Ball (roller coaster): Cannon Ball is a wooden roller coaster at Lake Winnepesaukah amusement park. Designed by John C. Allen and built by Philadelphia Toboggan Company (today called Philadelphia Toboggan Coasters), the roller coaster opened in 1967 and quickly became one of the signature attractions at the park. It is one of four roller coasters at the park.
Document 5: Old Mill (ride): An old mill is a type of amusement park ride with unaccompanied boats floated on guideways through dark tunnels. These themed dark rides originated in the late 19th century and are known by a variety of names, including tunnel of love and river cave. While generally considered a gentle ride, a variation that ends with a climactic splashdown, similar to the modern-day log flume, is known as a mill chute.
Document 6: Geauga Lake: Geauga Lake is an abandoned theme park in Bainbridge Township and Aurora, Ohio, United States. Established in 1887 in what had been a local recreation area adjacent to a lake of the same name, the first amusement ride was added in 1889, and the park's first roller coaster – later known as the Big Dipper – was built in 1925. In 1969, the park was sold to Funtime, Inc., and was expanded over the years with additional rides and amenities. Further expansion occurred in the mid and late 1990s after Funtime's acquisition by Premier Parks in 1995. Prior to the 2000 season, soon after Premier Parks acquired Six Flags, the park was re-branded as Six Flags Ohio and four new roller coasters were added. A year later, Six Flags bought the adjacent SeaWorld Ohio and combined the two parks under the name Six Flags Worlds of Adventure.
Document 7: Dark ride: A dark ride or ghost train is an indoor amusement ride on which passengers aboard guided vehicles travel through specially lit scenes that typically contain animation, sound, music, and special effects.
Document 8: Mill Race (log flume): Mill Race was a log flume ride that operated between 1963 and 1993 at the Cedar Point amusement park in Sandusky, Ohio. When it opened in 1963, Mill Race was only the second such log flume ride to ever operate in the world (the first being El Aserradero [The Sawmill] at Six Flags Over Texas, which had opened earlier that same year). Mill Race was ultimately removed from the park in 1993 to prepare for the opening of Raptor in 1994.
Document 9: Ebenezer Floppen Slopper's Wonderful Water slides: Ebenezer Floppen Slopper's Wonderful Water slides is an abandoned waterpark located on a large hill on Roosevelt Road and Route 83 in Oakbrook Terrace, Illinois. It first opened on July 5, 1980 with two 800 foot concrete water slides and gradually added 5 additional slides and a wading pool. The water park became a major summer attraction for residents of surrounding towns and communities as people lined up for rides down the large winding slides. When the two main slides first began operation, people slid down in groups of up to eight people at a time on rubber mats. The 5 other slides added to the park included 2 flat racer slides in which people slid down head first on folded rubber mats, 2 semi enclosed tube body slides, and a smaller inner tube slide which emptied into a nearby wading pool. The slides were also unique in that they were lined with a blue rubber foam material which would prevent injuries from contacts with the slide walls. Due to the design of the 2 main large concrete slides, especially with the V-shaped configuration of their side walls, people could also slide quite high up the walls of the slides, especially when hitting a turn at high speeds. Around 1987, the large concrete slides were re surfaced with flat bottoms with humps and bumps in which people went down solo on inner tubes, getting bumped up and down and sideways as they went down the renovated slides and the park was re named "Doc River's Roaring Rapids water park."
Document 10: Splash Mountain: Splash Mountain is a log flume dark ride at Disneyland, Tokyo Disneyland, and the Magic Kingdom at the Walt Disney World Resort, based on the characters, stories, and songs from the 1946 Disney film "Song of the South". Although there are variations in the story and features between the three locations, each installation begins with a peaceful outdoor float-through that leads to indoor dark ride segments, with a climactic steep drop into a "briar patch" followed by an indoor finale. The drop is 50 ft .
