Definitely not the roughest airfield I've ever heard of (that would be 52NM, Timberon Airport, 5000 feet of gravel and deer nestled betweeen heavily forested mountains), but it looks to be pretty small-time.
It's got low intensity runway lights, is closed dusk to dawn, but at least it has an actual asphalt surface somebody apparently gives half a shit about although they don't bother clearing snow. The parking area for the planes (tie downs) looks to be rough/turf. The runway is 4000 feet, which is a little on the short side for anybody other than private planes with good lift to distance ratios (though there's plenty shorter in the world). You won't be seeing any gulfstreams or the like at that airport, the runway's too short, but it might be a convenient spot for someone in the area who owns a Piper, Cessna or Mooney who doesn't want to go all the way to Klamath Falls or Medford, much less Portland, to get to their plane.
