This appears to be a completely open runway located in Crow Wing County, a few miles southeast of Pine River and northeast of Jenkins. This landing strip is not outlined on Navteq road maps. It is shown (but only labeled as "Landing Strip") on the 1959 USGS topographic map. Over forty five minutes of web searching has turned up a grand total of nada.

Anyway, the Unidentified runway in this map is much longer and appears to always have been -- dating back to the topographic map from the 1950's. (I'm 99.9% certain this isn't Ultraflyte, Inc.)
Why it is not listed is a mystery to me. Perhaps a private owner has recently resurrected this field (new pavement & markings vs. old turf/gravel) and it's not yet been added to FAA records?
