Question: What is the highest point in the state where Hocking Hills is located?

full_context: Document 1: Portland, Oregon: Though much of downtown Portland is relatively flat, the foothills of the Tualatin Mountains, more commonly referred to locally as the ``West Hills '', pierce through the northwest and southwest reaches of the city. Council Crest Park, commonly thought of as the highest point within city limits, is in the West Hills and rises to an elevation of 1,073 feet (327 m) The city's actual high point is a little - known and infrequently accessed point (1,180 feet) near Forest Park. The highest point east of the river is Mt. Tabor, an extinct volcanic cinder cone, which rises to 636 feet (194 m). Nearby Powell Butte and Rocky Butte rise to 614 feet (187 m) and 612 feet (187 m), respectively. To the west of the Tualatin Mountains lies the Oregon Coast Range, and to the east lies the actively volcanic Cascade Range. On clear days, Mt. Hood and Mt. St. Helens dominate the horizon, while Mt. Adams and Mt. Rainier can also be seen in the distance.
Document 2: Campbell Hill (Ohio): Campbell Hill is, at 1,550 feet (470 m), the highest point in elevation in the U.S. state of Ohio. Campbell Hill is located within the city of Bellefontaine, 2 miles (3.2 km) northeast of downtown.
Document 3: Oklahoma: Oklahoma has four primary mountain ranges: the Ouachita Mountains, the Arbuckle Mountains, the Wichita Mountains, and the Ozark Mountains. Contained within the U.S. Interior Highlands region, the Ozark and Ouachita Mountains mark the only major mountainous region between the Rocky Mountains and the Appalachians. A portion of the Flint Hills stretches into north-central Oklahoma, and near the state's eastern border, Cavanal Hill is regarded by the Oklahoma Tourism & Recreation Department as the world's tallest hill; at 1,999 feet (609 m), it fails their definition of a mountain by one foot.
Document 4: Needles (Black Hills): The Needles of the Black Hills of South Dakota are a region of eroded granite pillars, towers, and spires within Custer State Park. Popular with rock climbers and tourists alike, the Needles are accessed from the Needles Highway, which is a part of Sylvan Lake Road (SD 87/89). The Cathedral Spires and Limber Pine Natural Area, a 637-acre portion of the Needles containing six ridges of pillars as well as a disjunct stand of limber pine, was designated a National Natural Landmark in 1976.
Document 5: Seattle: The city itself is hilly, though not uniformly so. Like Rome, the city is said to lie on seven hills; the lists vary, but typically include Capitol Hill, First Hill, West Seattle, Beacon Hill, Queen Anne, Magnolia, and the former Denny Hill. The Wallingford, Mount Baker, and Crown Hill neighborhoods are technically located on hills as well. Many of the hilliest areas are near the city center, with Capitol Hill, First Hill, and Beacon Hill collectively constituting something of a ridge along an isthmus between Elliott Bay and Lake Washington. The break in the ridge between First Hill and Beacon Hill is man-made, the result of two of the many regrading projects that reshaped the topography of the city center. The topography of the city center was also changed by the construction of a seawall and the artificial Harbor Island (completed 1909) at the mouth of the city's industrial Duwamish Waterway, the terminus of the Green River. The highest point within city limits is at High Point in West Seattle, which is roughly located near 35th Ave SW and SW Myrtle St. Other notable hills include Crown Hill, View Ridge/Wedgwood/Bryant, Maple Leaf, Phinney Ridge, Mt. Baker Ridge and Highlands/Carkeek/Bitterlake.
Document 6: Unglaciated Allegheny Plateau: One of the most spectacular and scenic areas in this region is located in southeast Ohio, and is known as the Hocking Hills region. This area, similar to but smaller than the Red River Gorge in the Cumberland Plateau in Kentucky, features cliffs, rock shelters and waterfalls.
Document 7: Falkenfelsen: The Falkenfelsen (Falcon Rock) is a granite rock formation in the Northern Black Forest of Germany's Baden-Württemberg state. One side of the formation is a cliff about high. From the Schwarzwaldhochstrasse (Black Forest Highway), two hiking trails lead through the formation and end at the shelter Herta-hut. The platform has a view over the northern Black Forest, with the Hornisgrinde in the south, Bühlerhöhe in the northeast and the valley of the Upper Rhine on the west.
Document 8: Elakala Falls: The Elakala Falls are a series of four waterfalls of Shays Run as it descends into the Blackwater Canyon in West Virginia. They are within Blackwater Falls State Park and are quite popular among photographers, with the ease of access for the first waterfall, and the relatively low traffic of the other waterfalls in the series. The first of the series of waterfalls is in height and is easily accessible from park trails. It is the second most popular waterfall in the park. From the official Elakala trail there is a bridge over the top of the first waterfall offering easy access and views. The remaining three waterfalls of the series are progressively more difficult to access, and have no official marked trails to them. The gorge is nearly 200 feet deep at this section accounting for the difficulty of the descent to the lower waterfalls of the series.
Document 9: Boston: Boston has an area of 89.6 square miles (232.1 km2)—48.4 square miles (125.4 km2) (54.0%) of land and 41.2 square miles (106.7 km2) (46.0%) of water. The city's official elevation, as measured at Logan International Airport, is 19 ft (5.8 m) above sea level. The highest point in Boston is Bellevue Hill at 330 feet (100 m) above sea level, and the lowest point is at sea level. Situated onshore of the Atlantic Ocean, Boston is the only state capital in the contiguous United States with an oceanic coastline.
Document 10: Goat Rock Beach: The sea stacks along the coast at Goat Rock Beach consist of rocks from the Franciscan Complex, formed within an era of plate collision along the western coast of North America. From about 200 to 30 million years ago, the North American Plate was in continual collision with the Farallon Plate. A variety of rock types resulted from this collision, including pillow basalt, chert, and marine sandstone. During the plate collisions, these rocks were considerably faulted and crushed into melange, which is a mixture of ground-up matrix and resistant pockets of rock floating within. When melange is eroded by wave action, the softer part of the matrix is washed away, leaving the more resistant blocks exposed in the ocean as sea stacks. Goat Rock is such a flat topped sea stack comprised by a block of resistant greywacke.
Document 11: Tennessee: The highest point in the state is Clingmans Dome at 6,643 feet (2,025 m). Clingmans Dome, which lies on Tennessee's eastern border, is the highest point on the Appalachian Trail, and is the third highest peak in the United States east of the Mississippi River. The state line between Tennessee and North Carolina crosses the summit. The state's lowest point is the Mississippi River at the Mississippi state line (the lowest point in Memphis, nearby, is at 195 ft (59 m)). The geographical center of the state is located in Murfreesboro.
Document 12: West Hawk Lake: West Hawk Lake is located in the Whiteshell Provincial Park in southeastern Manitoba, Western Canada. The central portion of the lake is formed by the West Hawk crater, caused by a meteor impact into an ancient rock bed composed of mostly granite. Granite cliffs surround parts of the lake. This area is also known as part of the Canadian Shield that was formed billions of years ago. Parts of the Whiteshell park have elaborate petroforms that were made by First Nation peoples, possibly over a thousand years ago. There are petroform shapes of turtles, snakes, humans and geometrical patterns, often found upon pink granite ridges that were shaped during the last ice age.
Document 13: Hocking Hills: The Hocking Hills is a deeply dissected area of the Allegheny Plateau in Ohio, primarily in Hocking County, that features cliffs, gorges, rock shelters, and waterfalls. The relatively extreme topography in this area is due to the Blackhand Sandstone (so named because of Native American graphics on the formation near Newark, Ohio), a particular formation that is thick, hard and weather-resistant, and so forms high cliffs and narrow, deep gorges.
Document 14: Cheaha Mountain: Cheaha Mountain / ˈtʃiːhɔː /, often called Mount Cheaha, is the highest natural point in the U.S. state of Alabama. It is located a few miles northwest of the town of Delta in Cheaha State Park, which offers a lodge, a restaurant, and other amenities.
Document 15: Feigenbaumklippe: The Feigenbaumklippe is a rock formation in the Oker valley in the Harz mountains of central Germany. They lie on the hiking trail from the "Kästeklippen" crags to Romkerhall Waterfall. These granite rocks, which show clear signs of "wool sack weathering" ("Wollsackverwitterung") are a favourite destination for hikers and offer a good view of the valley towards the west. The observation point has safety railings.
