ice runways
Several Antarctic research stations use runways carved directly into sea ice or glacial ice, with some supporting aircraft as large as the C-17 Globemaster.

McMurdo Station in Antarctica operates multiple runway surfaces depending on the season: a sea ice runway in winter and spring, a compacted snow runway on the Ross Ice Shelf in summer, and a white ice runway on the Pegasus ice field. These runways must be periodically resurfaced and monitored for cracks and melt. When conditions change, the entire runway location may shift. Landing on ice requires specialized procedures and timing.
