Query: Crossing muons in Icecube at highest energy: Cornerstone to neutrino
  astronomy   Highest energy neutrino events (contained) in cubic km ICECUBE detector
resulted in last three years to be as many as $37-2=35$ signals (two of those
having been recently discharged); these tens-hundred TeV (32 energetic events)
up to rarest (only 3) PeV cascade showers, proved to have an extraterrestrial
origin. The UHE neutrino flavor transition from a $\nu_{\mu}$ atmospheric
dominance (over $\nu_{e}$ showers at TeV energy), toward a higher energy shower
cascade ($\nu_{e}$, $\nu_{\tau}$) events at few tens TeV up to PeV energy is a
hint of such a fast extraterrestrial injection. The majority (28 out of 35) of
all these events are spherical cascade; their consequent smeared map is
inconclusive. The additional rarest $9-2=7$ muon tracks, while being sharp in
arrival directions, did not offer any correlated clustering nor any overlapping
within known sources. We recently suggested that the highest energy (tens-TeV)
crossing muon along the ICECUBE, mostly at horizons or upcoming, are the ideal
tool able to reveal soon such clustering or even any narrow angle pointing to
known (IR, X, Radio or $\gamma$) sources or self-correlation in rare doublet or
triplet: a last hope for a meaningful and short-time $\nu$ Astronomy. Any
crossing muons clustering along galactic sources or within UHECR arrivals might
also probe rarest UHECR event made by nuclei or neutrons. Within three years of
ICECUBE data all the non-contained crossing highest energy muons above few tens
TeV may be several dozens, possibly around $54$ (27 for upward ones), mostly
enhanced along horizontal edges, painting known sources and/or self-correlating
in doublets or rarest triplet (if steady or transient nearby source are at
sight). Recent preliminary ICECUBE presentation on crossing muons are
consistent with present preliminary muon rate estimate.
