  36 CFR §2.17 – AIRCRAFT and AIR DELIVERY
  
  
  (a)(1) The use of aircraft on lands or waters within the park other than at locations designated by special regulations is prohibited.
  Death Valley’s special regulations at 36 CFR 7.26(e) authorizes the
  use of aircraft only at the following locations:
  
  
  Death Valley Airport, latitude N 36°27’50”, longitude W 116°52’50”, commonly known as the Furnace Creek Airport.
  Stovepipe Wells Airport, latitude N 36°36’15”, longitude W 117°09’30”.
  The Saline Valley Warm Springs Airfield, latitude N 36° 48.41”, longitude W 117° 46.90”, commonly known as the Chicken Strip, is open
  pending special regulation.
  
  
  
  The landing of aircraft at locations other than those listed above,
  such as for wildlife research, is permitted only under conditions of a
  permit issued by the superintendent.
  
  Aircraft have a significant potential for impacting park resources and
  human safety. By requiring permits for these activities, the
  superintendent can manage these activities and mitigate negative
  impacts.
