Union Glacier Blue-Ice Runway is one of the world's most remote and extraordinary airstrips, located deep in the Heritage Range of Antarctica at approximately 79°S latitude. Operated seasonally by ALE (Antarctic Logistics and Expeditions), it serves as a critical gateway for scientific expeditions, mountaineers, and South Pole traverse operations. The runway is not paved but instead uses the naturally compacted blue-ice surface of Union Glacier, requiring no construction yet capable of handling wheeled intercontinental aircraft such as the Ilyushin Il-76.
- ALE Base Camp Facility — A seasonal tent-and-modular-structure camp serving as the sole passenger processing and logistics hub on the glacier.
- Tracked and wheeled oversnow vehicles operated by ALE staff
- Ski-equipped aircraft transfers to remote field camps
- Guided snowcat transport to South Pole traverse routes
- ALE Union Glacier Camp (seasonal expedition tents)
- South Pole Overland Traverse field camps (remote)
All meals at Union Glacier are provided within the ALE base camp mess facility, offering hot communal dining prepared by on-site staff for expedition members and transiting passengers. No commercial restaurants or outside food options exist anywhere near the runway. Travellers should expect hearty, calorie-dense expedition-style catering suited to extreme cold-weather operations.
- Operations run only during the Antarctic summer season, typically November through January, when daylight is continuous.
- All travellers must be pre-cleared and briefed by ALE before arrival; independent access to this runway is not possible.
- Extreme weather can delay or cancel flights with little notice — build significant schedule buffer into any connecting travel plans.
- Dress in full polar expedition gear at all times on the ice; temperatures regularly drop below -20°C even in summer.
