Some approaches have a snowflake icon on their plates, indicating the airport is a Cold Temperature Airport. Altimeters are affected by changes in temperature, and very cold temps can cause the altimeter to indicate higher than the aircraft is actually flying, risking getting to close to obstructions. the FAA put in place procedures for correcting minimum altitudes when the temperature drops below limits at certain airports.
