MEMALOOSE USFS (25U) sits near Imnaha, Oregon. Field elevation is 6,708 ft MSL. The airport has one runway. Runway 17/35 is 3,300 ft long and surfaced with dirt. There is no control tower. CTAF is 122.9. No ILS approaches are published.
Pattern altitude is not published. Use standard 1,000 ft AGL for light piston operations unless the current FAA Chart Supplement says otherwise. At this elevation, performance planning matters. The field also has terrain issues that deserve attention on both ends. Runway 17 slopes up 2.5 percent to the south. Runway 35 can produce downdrafts on short final because of the drop in terrain. The runway ends are not in line of sight with each other.
Published remarks also call out loose rocks on the surface. The south 1,000 feet is rough and overgrown with weeds. Runway 35 has a berm along the left shoulder for about 500 feet. The threshold is marked by white rocks at the runway end. Livestock and wildlife have been reported on and near the airport. The field is closed in winter. No on-field FBOs are listed, so verify services with the airport operator or call the field directly before you go.
