Context_1 : Mount Greylock is the highest natural point in Massachusetts at 3489 ft . Its peak is located in the northwest corner of the state in the western part of the town of Adams (near its border with Williamstown) in Berkshire County.

Its depth is around 820 ft , but in some locations, it can increase up to 1000 ft . Palo Duro Canyon (from the Spanish meaning "hard wood") has been named "The Grand Canyon of Texas" both for its size and for its dramatic geological features, including the multicolored layers of rock and steep mesa walls similar to those in the Grand Canyon.

Context_6 : By the Treaty of Old Crossing (1863) and the Treaty of Old Crossing (1864), the Pembina and Red Lake bands of the Ojibwe, then known as Chippewa Indians, purportedly ceded to the United States all of their rights to the Red River Valley. On the Minnesota side, the ceded territory included all lands lying west of a line running generally southwest from the Lake of the Woods to Thief Lake, about 30 mi west of Red Lake, and then angling southeast to the headwaters of the Wild Rice River near the low-lying divide separating the watershed of the Red River of the North from the watershed of the Mississippi River. On the North Dakota side, the ceded territory included all of the Red River Valley north of the Sheyenne River. The total land area, roughly 127 mi wide east to west and 188 mi long north to south, consisted of nearly 11000000 acre of rich prairie land and forests. Context_7 : The Red River Showdown, commonly called the Red River Rivalry, the Red River Classic, or the Red River Shootout, is an American college football rivalry game played annually at the Cotton Bowl stadium in Dallas, Texas, during the second weekend of the State Fair of Texas in October. The participants are the Oklahoma Sooners football team of the University of Oklahoma and the Texas Longhorns football team of the University of Texas at Austin. The game is played the week following the State Fair Classic featuring Prairie View A&M University and Grambling State University. The series is one of the major rivalries in NCAA football and in all of American sports. The name is derived from the Red River that forms part of the boundary between Texas and Oklahoma that has in the past caused conflict between the two states, most notably the 1931 Red River Bridge War. Context_8 : Torrent Falls is a landmark outdoor residential property near the small community of Torrent, Kentucky, USA, which is near Natural Bridge State Park, Red River Gorge and Daniel Boone National Forest in Kentucky.

Context_9 : The Red River Floodway (French: "Canal de dérivation de la rivière Rouge" ) is an artificial flood control waterway in Western Canada, first used in 1969. It is a 47 km long channel which, during flood periods, takes part of the Red River's flow around the city of Winnipeg, Manitoba to the east and discharges it back into the Red River below the dam at Lockport. It can carry floodwater at a rate of up to 140000 cuft/s , expanded in the 2000s from its original channel capacity of 90000 cuft/s . It was built partly in response to the disastrous 1950 Red River flood. Context_10 : The Red River Canyon affair, or the Battle of Red River Canyon, was a military action fought during the Taos Revolt of the Mexican-American War.

Answer: Pottsville Escarpment
Output: Torrent Falls is near a canyon system on the Red River that is geologically part of what?
