Question: Which airport is further south, Aniak Airport or Jackson Hole Airport?
Context: Blacktail Butte (7688 ft ) is a butte mountain landform rising from Jackson Hole valley in Grand Teton National Park in the U.S. state of Wyoming.  Blacktail Butte was originally named "Upper Gros Ventre Butte" in an early historical survey conducted by the U.S. Geological Survey.  Most of Blacktail Butte is densely forested with a mixed fir forest of lodgepole pine, Douglas fir and Engelmann spruce, with scattered pockets of aspen.  There are several large sedimentary rock outcroppings, which are used by rock climbers.  This butte is a principal landmark in Jackson Hole, with much of the Jackson Hole valley floor and many portions of the Teton Range visible from its hillsides. Jackson Hole Airport (IATA: JAC, ICAO: KJAC, FAA LID: JAC) is a United States public airport located seven miles (11 km) north of Jackson, in Teton County, Wyoming.  In 2015, it was the busiest airport in Wyoming by passenger traffic with 313,151 passengers.  During peak seasons, Jackson Hole has nonstop airline service from 13 destinations throughout the United States including New York–JFK, Chicago–O'Hare, and Los Angeles International Airport.  During shoulder seasons, airline service is limited to the nearby hubs of Salt Lake City and Denver.  The airport is served year-round by Delta Connection and United Express and seasonally by Delta (mainline), United (mainline), Frontier Airlines and American. Teton National Forest was first established by the General Land Office on February 22, 1897 as the Teton Forest Reserve with 892440 acre .  A commission was established in 1896 to plan for a system of national forest reserves, recommending an expansion of the territory protected by the Yellowstone Timberland Reserve.  President Grover Cleveland's 1897 proclamation established a protected area encompassing the northern end of Jackson Hole, extending from the south boundary of the Yellowstone Forest Reserve south to the area of the Gros Ventre River, and from the Idaho border in the west to the area of the Continental Divide in the east.  Much of this area would eventually be incorporated into Grand Teton National Park.  In 1902 the southern porion of the Yellowstone reserve was added, while the Teton Reserve was greatly expanded to the south and east while excluding the southern portion of Jackson Hole around the town of Jackson. The Jackson Hole Mountain Resort (JHMR) is a ski resort in the western United States, at Teton Village, Wyoming.  In the Teton Range of the Rocky Mountains, it is located in Teton County, 12 mi northwest of Jackson and due south of Grand Teton National Park.  It is named after the historically significant Jackson Hole valley and is known for its steep terrain and a large continuous vertical drop of 4,139 ft . Aniak Airport (IATA: ANI, ICAO: PANI, FAA LID: ANI) is a state owned, public use airport located in Aniak, a city in the Bethel Census Area of the U.S. state of Alaska.  Its location on the Kuskokwim River also allows for the landing of seaplanes. Hoot In The Hole: The Story of the Jackson Hole Hootenanny is a 2008 music documentary that tells the story of the Jackson Hole Hootenanny, a bluegrass and folk music concert that takes place every Monday evening in Jackson Hole, Wyoming.  Directed by documentary filmmaker Juliet Sonnenberg throughout 2006 and 2007, "Hoot In The Hole" memorializes the show's 14-year history through a number of interviews with weekly performers at the Hootenanny such as Anne and Pete Sibley, John Byrne Cooke, and John Kuzloski, as well as performances from recording artists such as Tom Rush, Ramblin' Jack Elliott, the Wilders and The Hot Club of Cowtown. Jackson Hole National Monument was a wildlife reserve in Jackson Hole, most of which is now a part of Grand Teton National Park in Wyoming, United States.  It was created by executive order by Franklin Delano Roosevelt in 1943, and met with considerable opposition from Wyoming legislators.  Roosevelt later vetoed a bill that would have disestablished it.  Jackson Hole is named after a fur trapper named Davey Jackson. Jackson Hole Aerial Tram is located in Jackson Hole, Wyoming and has become an iconic symbol of the town.  Located at Jackson Hole Mountain Resort, it takes people to the top of Rendezvous Mountain.  The first tram started operation on July 31, 1966, while the second tram started operation on December 20, 2008.  The current tram is 12463 ft in length.  Starting at an elevation of 6311 ft , it takes passengers up to an elevation of 10450 ft in approximately nine minutes.  It can hold up to 100 people plus an operator.  The original tram carried 62 skiers and 1 conductor . The Jackson Lake Ranger Station is the last Depression-era U.S. Forest Service ranger station in its original location in Grand Teton National Park.  When first established, the park comprised only the mountainous terrain above Jackson Hole, while the remainder of what would eventually become the park was administered by the Forest Service as part of Teton National Forest.  The Jackson Lake Station was built in 1933 as close as possible to Park Service property as possible as a kind of resistance to the park's expansion.  The station was one of five Forest Service stations in the area, and was taken over by the National Park Service when Jackson Hole National Monument was established in 1943, later becoming an enlarged Grand Teton National Park.  It is the only such station not to have been moved or altered by the Park Service. The establishment of Grand Teton National Park took place over a period spanning more than 50 years.  Located in the northwestern region of the U.S. state of Wyoming, Grand Teton National Park is 10 mi south of Yellowstone National Park which was established in 1872, when Wyoming, Idaho and Montana were still territories and the region was very sparsely settled.  By the late 19th century, conservationists were working to provide further protection to surrounding regions, leading President Grover Cleveland to create the Teton Forest Reserve, which included a portion of northern Jackson Hole.  By 1902, the reserve had been combined into the Yellowstone Forest Reserve, then was divided again in 1908 by President Theodore Roosevelt, establishing the Teton National Forest, which protected most of the Teton Range.  By 1907, the U.S. Bureau of Reclamation had constructed a temporary dam at the Snake River outlet of Jackson Lake.  This dam failed in 1910 and a new concrete Jackson Lake Dam replaced it by 1911.  The dam was further enlarged in 1916, raising lake waters 39 ft as part of the Minidoka Project, designed to provide irrigation for agriculture in the state of Idaho.  Though efforts to protect the Teton Range and Jackson Hole as part of an expanded Yellowstone National Park dated back to the late 19th century, proposals to construct more dams on some of the other lakes in Jackson Hole led Yellowstone National Park superintendent Horace Albright to block such efforts.  Albright was originally an advocate of the expanded Yellowstone plan which was very unpopular with local residents.  By the mid-1920s local sentiment had changed as a result of proposals for a new national park including only the Teton Range and six lakes at the base of the range.  With the general agreement of prominent Jackson Hole residents to this plan, President Calvin Coolidge signed the executive order establishing the 96000 acre Grand Teton National Park on February 26, 1929.
