The magnetogram of this KGA shows 3 entrances. A suspected entrance near the north side of this KGA has been lost to a house. The southeastern entrance would allow the light of the rising sun to fall through at some unremarkable date in late winter.
The field where the KGA lies in slopes less than 3 degrees, and the direction of the southern entrance deviates less than 20° from the upslope direction. With slightly unequal erosion an assumption of a previously closer upslope orientation appears acceptable.
