Desert View Flight-free Zone. That airspace extending from the surface up to but not including 14,500 feet MSL within an area bounded by a line beginning at Lat. 35°59′58″ N., Long. 111°52′47″ W.; thence east to Lat. 36°00′00″ N., Long. 111°51′04″ W.; thence north to 36°00′24″ N., Long. 111°51′04″ W.; thence east to 36°00′24″ N., Long. 111°45′44″ W.; thence north along the GCNP boundary to Lat. 36°14′05″ N., Long. 111°48′34″ W.; thence southwest to Lat. 36°12′06″ N., Long. 111°51′14″ W.; to the point of origin; but not including the airspace at and above 10,500 feet MSL within 1 nautical mile of the western boundary of the zone. The corridor to the west between the Desert View and Bright Angel Flight-free Zones, is designated the “Zuni Point Corridor.” This corridor is 2 nautical miles wide for commercial air tour flights and 4 nautical miles wide for transient and general aviation operations.
Bright Angel Flight-free Zone. That airspace extending from the surface up to but not including 14,500 feet MSL within an area bounded by a line beginning at Lat. 35°58′39″ N., Long. 111°55′43″ W.; north to Lat. 36°12′41″ N., Long. 111°53′54″ W.; northwest to Lat. 36°18′18″ N., Long. 111°58′15″ W.; thence west along the GCNP boundary to Lat. 36°20′11″ N., Long. 112°06′25″ W.; south-southwest to Lat. 36°09′31″ N., Long. 112°11′15″ W.; to Lat. 36°04′16″ N., Long. 112°17′20″ W.; thence southeast along the GCNP boundary to Lat. 36°01′54″ N., Long. 112°11′24″ W.; thence clockwise via the 4.3-nautical mile radius of the Grand Canyon National Park Airport reference point (Lat. 35°57′08″ N., Long. 112°08′49″ W.) to Lat. 35°59′37″ N., Long. 112°04′29″ W.; thence east along the GCNP boundary to the point of origin; but not including the airspace at and above 10,500 feet MSL within 1 nautical mile of the eastern boundary or the airspace at and above 10,500 feet MSL within 2 nautical miles of the northwestern boundary. The corridor to the east, between this flight-free zone and the Desert View Flight-free Zone, is designated the “Zuni Point Corridor.” The corridor to the west, between the Bright Angel and Toroweap/Shinumo Flight-free Zones, is designated the “Dragon Corridor.” This corridor is 2 nautical miles wide for commercial air tour flights and 4 nautical miles wide for transient and general aviation operations. The Bright Angel Flight-free Zone does not include the following airspace designated as the Bright Angel Corridor: That airspace one-half nautical mile on either side of a line extending from Lat. 36°14′57″ N., Long. 112°08′45″ W. and Lat. 36°15′01″ N., Long. 111°55′39″ W.
Toroweap/Shinumo Flight-free Zone. That airspace extending from the surface up to but not including 14,500 feet MSL within an area bounded by a line beginning at Lat. 36°05′44″ N., Long. 112°19′27″ W.; north-northeast to Lat. 36°10′49″ N., Long. 112°13′19″ W.; to Lat. 36°21′02″ N., Long. 112°08′47″ W.; thence west and south along the GCNP boundary to Lat 36°10′58″ N., Long. 113°08′35″ W.; south to Lat. 36°10′12″ N., Long. 113°08′34″ W.; thence in an easterly direction along the park boundary to the point of origin; but not including the following airspace designated as the “Tuckup Corridor”: at or above 10,500 feet MSL within 2 nautical miles either side of a line extending between Lat. 36°24′42″ N., Long. 112°48′47″ W. and Lat. 36°14′17″ N., Long. 112°48′31″ W. The airspace designated as the “Fossil Canyon Corridor” is also excluded from the Toroweap/Shinumo Flight-free Zone at or above 10,500 feet MSL within 2 nautical miles either side of a line extending between Lat. 36°16′26″ N., Long. 112°34′35″ W. and Lat. 36°22′51″ N., Long. 112°18′18″ W. The Fossil Canyon Corridor is to be used for transient and general aviation operations only.
Sanup Flight-free Zone. That airspace extending from the surface up to but not including 8,000 feet MSL within an area bounded by a line beginning at Lat. 35°59′32″ N., Long. 113°20′28″ W.; west to Lat. 36°00′55″ N., Long. 113°42′09″ W.; southeast to Lat. 35°59′57″ N., Long. 113°41′09″ W.; to Lat. 35°59′09″ N., Long. 113°40′53″ W.; to Lat. 35°58′45″ N., Long. 113°40′15″ W.; to Lat. 35°57′52″ N., Long. 113°39′34″ W.; to Lat. 35°56′44″ N., Long. 113°39′07″ W.; to Lat. 35°56′04″ N., Long. 113°39′20″ W.; to Lat. 35°55′02″ N., Long. 113°40′43″ W.; to Lat. 35°54′47″ N., Long. 113°40′51″ W.; southeast to Lat. 35°50′16″ N., Long. 113°37′13″ W.; thence along the park boundary to the point of origin.
