Possible evidence for a $5.86 PeV$ cosmic ray enhancement

A blind search has been made for cosmic ray sources of neutral hadrons yielding a peak just above the knee, which has resulted in possible evidence for a peak at $5.86\pm 0.75 PeV.$ This search was motivated by a 1999 claim by this author of such a peak at $4.5\pm 2.2 PeV,$ and also some recent results by at least three experiments showing a $E\approx 5.6 PeV$ peak in the all-particle cosmic ray spectrum.
