(a) 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&min;58&sec; N., Long. 111°52&min;47&sec; W.; thence east to Lat. 36°00&min;00&sec; N., Long. 111°51&min;04&sec; W.; thence north to 36°00&min;24&sec; N., Long. 111°51&min;04&sec; W.; thence east to 36°00&min;24&sec; N., Long. 111°45&min;44&sec; W.; thence north along the GCNP boundary to Lat. 36°14&min;05&sec; N., Long. 111°48&min;34&sec; W.; thence southwest to Lat. 36°12&min;06&sec; N., Long. 111°51&min;14&sec; 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.

(b) 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&min;39&sec; N., Long. 111°55&min;43&sec; W.; north to Lat. 36°12&min;41&sec; N., Long. 111°53&min;54&sec; W.; northwest to Lat. 36°18&min;18&sec; N., Long. 111°58&min;15&sec; W.; thence west along the GCNP boundary to Lat. 36°20&min;11&sec; N., Long. 112°06&min;25&sec; W.; south-southwest to Lat. 36°09&min;31&sec; N., Long. 112°11&min;15&sec; W.; to Lat. 36°04&min;16&sec; N., Long. 112°17&min;20&sec; W.; thence southeast along the GCNP boundary to Lat. 36°01&min;54&sec; N., Long. 112°11&min;24&sec; W.; thence clockwise via the 4.3-nautical mile radius of the Grand Canyon National Park Airport reference point (Lat. 35°57&min;08&sec; N., Long. 112°08&min;49&sec; W.) to Lat. 35°59&min;37&sec; N., Long. 112°04&min;29&sec; 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.
