What is the runway length at Cascade Airport (U70)?
Cascade Airport, identified as U70, has a single paved runway, 12/30, measuring 4,300 feet long and 60 feet wide with an asphalt surface. There is no parallel or crosswind runway option at this field. Pilots should plan performance calculations around this single-runway configuration, particularly given the field elevation of 4,748 feet.
Are there noise abatement or runway preference procedures at U70?
Yes, Cascade Airport publishes a local procedure to avoid overflying the town of Cascade. When wind conditions permit, pilots are advised to land on Runway 30 and depart on Runway 12. This preference is intended to keep approach and departure paths clear of the town rather than routing directly over it.
Is fuel available at Cascade Airport (U70)?

The field operates on a seasonal attendance schedule, staffed 0900-1700 from December through April and 0800-1800 from May through November. Dispatchers should confirm fuel service against the current attendance window before planning a stop at U70.
What terrain or obstacle considerations apply near Runway 12 at Cascade Airport?
Cascade Airport reports a timbered ridge rising 300 feet above Runway 12, located 1.25 miles out on the extended centerline. This obstacle sits directly on the approach or departure path for that runway end. It is one of the operational factors behind the airport's published guidance to favor Runway 30 for landing and Runway 12 for departure when wind allows.
