Summit Camp

The station is located approximately from the east coast of Greenland, from the west coast (at Saattut, Uummannaq), and north-northeast of the historical ice sheet station Eismitte. The closest town is Ittoqqortoormiit, east-southeast of the station. The station, however, is not part of the Sermersooq municipality but falls within the bounds of the Northeast Greenland National Park. Summit Station consists of the Station Operations Facility (communications and galley), Mobile Science Facility, Atmospheric Watch Observatory, Berthing Module, Summit Mobile Garage, and supporting structures. The surface elevation at Summit Station has increased at an average of per year over the period 2008–2018. Accumulation is the single largest factor in elevation change. == History ==

Summit Station was originally established in April 1989 in support of the Greenland Ice Sheet Project Two (GISP2) deep ice coring effort. A ski-equipped C-130 from the New York Air National Guard performed an open snow landing near the site, bringing the put-in team consisting of Mark Twickler, Jay Klink, Michael Morrison, and two navigation specialists; Doug Roberts and Jim Normandeau who located the exact location chosen for the GISP2 drilling site, established a camp, and laid out the runway. Subsequent flights brought in additional materials and personnel needed to build the station. Two major structures were planned and built: The Big House, an insulated panel building (housing a galley, common space, and office), elevated to minimize snow drifts; and a geodesic drill dome to house the deep drill. Extensive under-snow trenches were also constructed to house the core handling, processing, and storage facilities. Many smaller Weatherport hut buildings and tents were also erected as storage and shop areas, as well as sleeping quarters. These were erected and taken down each season. On July 1, 1993, the bedrock was reached. Originally only occupied in the summer, the station has been staffed year-round since 2003, with a winter population of four to five. The Greenland Telescope is yet to be relocated here, though preparations are still underway. == Climate ==

The climate is classified as ice cap, with no month having a mean temperature exceeding . Typical daily maximum temperatures at Summit Camp are around in winter (January) and in summer (July). Winter minimum temperatures are typically about and only rarely exceed . The highest temperature at Summit Station was , recorded on 13 July 2012 and on 28 July 2017; the lowest recorded temperature was on 22 December 1991, On 6 July 2017 the site recorded the lowest temperature in the northern hemisphere for the month of July at . On August 14, 2021, it rained throughout the entire day at Summit Camp, marking the first time since record-keeping began in 1989 that precipitation had fallen in liquid form at Greenland's glacial summit. }} == Transport == During the summer months, the station is accessed via Kangerlussuaq Airport with LC-130 Hercules aircraft which land on a snow runway, which is prepared and regularly groomed for ski-equipped aircraft. ==See also==
