question: Which national forest on Roan Mountain was created in 1920?
answer: Cherokee National Forest
context: Title: Palouse National Forest
  Passage: The Palouse Forest Reserve and after March 4, 1907, the Palouse National Forest was established by Presidential Proclamation (34 U.S. Statutes at Large 3293) on March 2, 1907 and was one of President Theodore Roosevelt's Midnight forests, created before the federal law banning new forest reserves in six western states, including Idaho, became effective.  The conventional wisdom has the name ‘palouse’ being derived from the French term for the large treeless plain region in eastern Washington stretching into Idaho: the Palouse, a word meaning grassy spot or place.  However, Boone says that the name could originate from the name of a major village of Palouse Indians, Palus, located at the confluence of the Palouse and Snake Rivers.  'Palus' is the Sachapin Indian word for “something sticking down in the water,” in this case the something was a large rock, thought to be a beaver’s heart, and which had an important religious significance for the Palouse Indians.  The Palouse National Forest had its administrative headquarters in the town of Wallace, Idaho for its 15-month existence and was administered by the U.S. Forest Service with 194404 acre .  With the issuance of Executive Order 843 by President Roosevelt on June 26, 1908, with an effective date of July 1, 1908, the entire forest was absorbed by the Coeur d'Alene National Forest and the area ceased to be an independently administered national forest.  The lands of the former Palouse National Forest were then administered as part of the Coeur d’Alene National Forest for three years before being combined with other lands to establish the St. Joe National Forest on July 1, 1911.  The area of the former Palouse National Forest formed the western portion of the St. Joe National Forest.  Once transferred in 1911, the area of the Palouse National Forest became the Palouse Ranger District of the St. Joe National Forest and is still considered part of the St. Joe National Forest.  However, it has been administered by the Clearwater National Forest since the 1973 administrative merger of the Kaniksu National Forest, Coeur d’Alene, and St. Joe National Forests into the Idaho Panhandle National Forests.
  Title: Roan Mountain (Roan Highlands)
  Passage: Roan Mountain is the highpoint of the Roan-Unaka Range of the Southern Appalachian Mountains, located in the Southeastern United States.  The mountain is clad in a dense stand of Southern Appalachian spruce-fir forest, and includes the world's largest natural rhododendron garden, and the longest stretch of grassy bald in the Appalachian range.  The Cherokee National Forest and Pisgah National Forest converge atop the mountain, with Roan Mountain State Park located near its northern base.  The Appalachian Trail crosses most of the Roan's crest.  The Roan High Knob Shelter is the highest backcountry shelter on the entire 2174 mi trail.
  Title: Coconino National Forest
  Passage: The Coconino National Forest is a 1.856-million acre (751,000 ha) United States National Forest located in northern Arizona in the vicinity of Flagstaff.  Originally established in 1898 as the "San Francisco Mountains National Forest Reserve", the area was designated a U.S. National Forest in 1908 when the San Francisco Mountains National Forest Reserve was merged with lands from other surrounding forest reserves to create the Coconino National Forest.  Today, the Coconino National Forest contains diverse landscapes, including deserts, ponderosa pine forests, flatlands, mesas, alpine tundra, and ancient volcanic peaks.  The forest surrounds the towns of Sedona and Flagstaff and borders four other national forests; the Kaibab National Forest to the west and northwest, the Prescott National Forest to the southwest, the Tonto National Forest to the south, and the Apache-Sitgreaves National Forest to the southeast.  The forest contains all or parts of ten designated wilderness areas, including the Kachina Peaks Wilderness, which includes the summit of the San Francisco Peaks.  The headquarters are in Flagstaff.  There are local ranger district offices in Flagstaff, Happy Jack, and Sedona.
