Question: What is the name of this area in northern Georga that comprises two United States National Forests with a combined total area of 866468 acres, and which surrounds the James H. Floyd State Park?
Context: National Grassland is a classification of protected and managed federal lands in the United States authorized by Title III of the Bankhead–Jones Farm Tenant Act of 1937.  For administrative purposes, they are essentially identical to United States National Forests, except that grasslands are areas primarily consisting of prairie.  Like National Forests, National Grasslands may be open for hunting, grazing, mineral extraction, recreation and other uses.  Various National Grasslands are typically administered in conjunction with nearby National Forests. 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. 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. The Chattahoochee-Oconee National Forest in northern Georgia comprises two United States National Forests, the Oconee National Forest and Chattahoochee National Forest.  The combined total area of the Chattahoochee-Oconee National Forest is 866468 acre , of which the Chattahoochee National Forest comprises 750145 acre and the Oconee National Forest comprises 116232 acre .  The county with the largest portion of the forest is Rabun County, Georgia, which has 148684 acre within its boundaries. The Deschutes National Forest is a United States National Forest located in parts of Deschutes, Klamath, Lake, and Jefferson counties in central Oregon.  It comprises 1.8 e6acre along the east side of the Cascade Range.  In 1908, the Deschutes National Forest was established from parts of the Blue Mountains, Cascade, and Fremont National Forests.  In 1911, parts of the Deschutes National Forest were split off to form the Ochoco and Paulina National Forests, and parts of the Cascade and Oregon National Forests were added to the Deschutes.  In 1915, the lands of the Paulina National Forest were rejoined to the Deschutes National Forest.  A 1993 Forest Service study estimated that the extent of old growth in the forest was 348100 acre .  Within the boundaries of the Deschutes National Forest is the Newberry National Volcanic Monument, containing cinder cones, lava flows, and lava tubes.  The Deschutes National Forest as a whole contains in excess of 250 known caves. The Apache-Sitgreaves National Forest is a 2.76 e6acre United States National Forest which runs along the Mogollon Rim and the White Mountains in east-central Arizona and extending into the U.S. state of New Mexico.  Both forests are managed as one unit by USDA Forest Service from the forests Supervisors Office in Springerville, Arizona.  Apache-Sitgreaves has over 400 species of wildlife .  With its high elevation and cool summer breezes it is a popular weekend destination from the hot desert for Phoenix, Arizona residents.  The forest is divided into 5 Ranger Districts (Clifton, Alpine, Springerville, Lakeside, and Black Mesa) that span almost 300 mi from Clifton, Arizona in the east-central portion of Arizona to the eastern boundary of the Coconino National Forest in north-central Arizona.  The Apache-Sitgreaves National Forest borders the western and northern borders of the Fort Apache Indian Reservation.  It is located in parts of Greenlee, Apache, Navajo, and Coconino counties in eastern and east-central Arizona, and Catron County in western New Mexico.  The more northwesterly Sitgreaves National Forest portion lies adjacent to the north side of the Fort Apache Indian Reservation and is located entirely in Arizona, within Navajo, Apache, and Coconino counties.  It has a total area of 818,651 acre .  The more southeasterly and much larger Apache National Forest portion lies adjacent to the east side of the Fort Apache and the San Carlos Indian Reservations.  It lies on both sides of the border with New Mexico, in Greenlee, Catron, and Apache counties.  It has a total area of 1,813,601 acre . The Sam Houston National Forest, one of four National Forests in Texas, is located 50 miles north of Houston.  The forest is administered together with the other three United States National Forests and two National Grasslands located entirely in Texas, from common offices in Lufkin, Texas.  The units include Angelina, Davy Crockett, Sabine, and Sam Houston National Forests, plus Caddo National Grassland and Lyndon B. Johnson National Grassland.  There are local ranger district offices located in New Waverly. James H. Floyd State Park is a 561 acre (2.27 km²) Georgia State Park located near Summerville at the base of Taylor Ridge (Georgia).  The park is named after Democrat James H. "Sloppy" Floyd who served in the Georgia House of Representatives from 1953 until 1974 and was from the area.  Surrounded by rural countryside and the Chattahoochee National Forest, the park offers many activities, including camping, hiking and fishing.  In addition, the park contains two lakes that total 51 acres (0.21 km²) and a children’s playground.  The Pinhoti Trail is accessible through the park. The St. Joe National Forest is a U.S. National Forest located in the Idaho panhandle and is one of three forests that are aggregated into the Idaho Panhandle National Forests (the other two are the Coeur d'Alene and Kaniksu National Forests).  In descending order of land area St. Joe National Forest is located in parts of Shoshone, Latah, Clearwater, and Benewah counties.  It has a total area of 867882 acre . Tombigbee National Forest is a U.S. National Forest in eastern and northeastern Mississippi.  It is named for the nearby Tombigbee River.  It is divided geographically into two non-contiguous sections.  The larger southern section, about 60% of the total acreage, is located north of Louisville, in parts of Winston, Choctaw, and Oktibbeha counties in eastern Mississippi.  The smaller northern section, about 40% of the total acreage, is located northeast of Houston, in parts of Chickasaw and Pontotoc counties in northeastern Mississippi.  As a whole the forest lies, in descending order of land area, in Winston, Chickasaw, Choctaw, Pontotoc, and Oktibbeha counties.  The forest has a total area of 67,005 acres (105 sq mi, or 271 km²).  Headquarters of forest administration is in Jackson, as are those for all six National Forests in Mississippi, but local ranger district offices are located in Ackerman.  The forest contains the Owl Creek Mounds, which include five platform mounds built between 1100 and 1200 CE.
