Landing essentials
Whether you can land, whether you can refuel, and how customs works here.
Overview
Alpine Airport (46U) is a single-runway public-use field in Alpine, Wyoming, sitting at 5,637 feet elevation in mountainous terrain near the Idaho and Wyoming border. The airport is unattended, uncontrolled, and closed at night, with a voluntary dusk-to-dawn curfew that limits night landings to airpark residents. Business aviation accounts for the great majority of its recorded operations, and transient crews are asked to contact the airport manager before using the field due to local flying procedures unique to the terrain.

Operating constraints
Alpine Airport has published operating constraints in five categories: weight restrictions, runway notes, noise procedures, environmental and other notes.
Residential taxiways have their own established weight limits and require approval prior to use.
PAPI on runway 13 and MIRL on runway 13/31 are pilot-activated via CTAF.
Vegetation extending 3 feet above ground and terrain dropping 5 feet begin 60 feet from the runway end, across both sides of the centerline.
A 16-foot-high paved road, located 106 feet from the runway end, crosses the runway end.
Fences, buildings, and trees are located within 150 feet north and south of the runway 13/31 centerline.
On runway 31, from the displaced threshold, an obstruction clearance slope of 20:1 rises to a 45-foot tree located 480 feet from the end of the runway, 75 feet left of centerline.
For runway conditions in winter, contact the airport manager.
Runway conditions and braking action vary during winter months. Snowbanks may form along runway and taxiway edges during fall, winter, and spring months. Treacherous mountain terrain is in close proximity on all quadrants of the runway.
Avoid low-level flight over the city or east of the runway.
This is a noise-sensitive airport. Landing on runway 13 and takeoff on runway 31 are the preferred noise abatement procedures. Due to the proximity of the town of Alpine and airport housing, touch-and-go operations are prohibited.
There is a voluntary curfew from dusk to dawn. Night landings are limited to airpark residents only. Night takeoffs and landings are not advised for pilots unfamiliar with the terrain. Wildlife is present on and in the vicinity of the airport, including a bird and waterfowl hazard.
Airport closed at night.
Self-service fuel is available 24 hours a day with a credit card; full-service Jet A and avgas are also available but must be arranged in advance.

Frequently asked questions
What runway does 46U in Alpine, Wyoming offer?
Alpine Airport (46U) has a single asphalt runway, 13/31, measuring 5,827 feet long and 70 feet wide. This is also the airport's maximum paved surface length, so no other runway option exists at the field. Pilots should note noise abatement procedures favor landing on runway 13 and departing on runway 31. Touch-and-go operations are prohibited because of the proximity of the town of Alpine and airport housing.
Is fuel available at Alpine Airport (46U)?
Alpine Airport (46U) offers both 100LL avgas and Jet A. Self-service fuel is available 24 hours a day with a credit card. Full-service Jet A and avgas can also be arranged, but only in advance. Because the field is unattended, pilots needing full-service fuel should plan ahead rather than expect on-demand support.
Where is the nearest customs facility to 46U?
Alpine Airport (46U) has no onsite customs service. The nearest customs facility is at Salt Lake City International (KSLC), located approximately 149.69 nautical miles away. Crews requiring customs clearance near Alpine should plan their routing and timing around this distance rather than expect any onsite processing at the airport itself. This distance makes 46U impractical as a direct port of entry for international arrivals.
What obstacles or terrain hazards should pilots know about at 46U?
Alpine Airport (46U) is surrounded by treacherous mountain terrain in close proximity to all quadrants of the runway. Close-in obstructions include vegetation and terrain drop-offs starting 60 feet from the runway ends on both sides of the centerline, and a paved road crossing just 106 feet from the runway end. Fences, buildings, and trees sit within 150 feet of the runway centerline on both the north and south sides. Runway 31 also has an obstruction clearance slope of 20:1 rising to a 45-foot tree near the end of the runway. Wildlife, including birds and waterfowl, are also reported on and in the vicinity of the airport.
Are there operating restrictions at Alpine Airport beyond the runway itself?
Alpine Airport (46U) enforces a voluntary curfew from dusk to dawn, and night landings are limited to airpark residents only. Night takeoffs and landings are not advised for pilots unfamiliar with the surrounding terrain. Residential taxiways at the airport have their own separately established weight limits and require approval before use. Winter runway conditions vary and snowbanks may form along runway and taxiway edges in fall, winter, and spring, so pilots should contact the airport manager for current surface conditions.
