Lost River Airport (W12) is in Mazama, Washington. Field elevation is 2,415 ft MSL. This is a very small field with no listed runways in the data provided. The airport is closed from November 1 through April 1. CTAF is 122.9. No tower is published. No ILS approaches are published.

The published remarks matter here. Vehicles and pedestrians may be on the runway. Access roads are on both sides of the runway in the primary surface. Vehicles also cross the runway at various locations, mostly near the runway ends. Runway 11 is marked on a concrete pad. Trees about 60 ft tall are reported in the primary surface on both sides of runway 11/29. That means a careful low-level look is smart before you commit.

Pattern altitude is not published. Use the standard 1,000 ft AGL for light piston traffic unless the current FAA Chart Supplement says otherwise. There are no on-field FBOs listed. For clearance delivery, the published remark says to contact Seattle ARTCC at 253-351-3694. With the field sitting at 2,415 ft MSL in a mountain area, expect density altitude to matter on warm days. Verify current status and any local operating notes before you go.
