Glacier Bay Operations

1. Heavy flightseeing traffic is present in the Glacier Bay area from
   early May through the end of September. Aircraft can be found in any part of the park at various altitudes, with the greatest concentration in the shaded areas and passes on the following page.

2. Aircraft should have their landing light on at all times for improved traffic recognition and separation. Frequency 122.75 should be monitored while in this area for general tour flight activity position reporting.

3. It is advisable to check with local carriers or Park Service regarding air tour operations and sensitive areas for that particular day (i.e. heavy tour bookings, molting water fowl locations or seal pupping areas).

4. Adams Inlet (see outlined area on map) is a refuge for molting (flightless) ducks and geese from approximately July 1 – September 15. The inlet is also designated as non-motorized waters for the entire visitor season (May 1 – September 15) for protection of wildlife and visitor solitude. The NPS requests pilots transiting via the Endicott River to maintain as high an altitude as practical and to minimize the time spent over this area.

5. Motor vessels are banned from upper Muir Inlet (see outlined area on map) June 1 – July 15 to provide an opportunity for visitor solitude and wilderness recreation in the East Arm. Upper Muir Inlet is especially susceptible to engine noise due to its almost vertical canyon walls. Pilots are requested to adhere to the 2000 feet AGL minimum and to avoid prolonged circling when over this area.

6. Johns Hopkins Inlet (see outlined area on map) is closed to all vessels May 1 – June 30 to prevent disturbance to harbor seals during pupping. The NPS requests pilots strictly observe the recommended 2000 foot AGL minimum and to minimize time spent in this area during those dates.
