Naturally-occurring neutrinos span at least 19 orders of magnitude in energy, from the cosmic neutrino background at milli-eV scales to the highest-observed particles above 10 PeV. At the highest energies, above about 50 TeV, the majority of these particles have been known since 2013 to originate in distant astrophysical sources of unknown nature. These neutrinos provide not only our only direct information about the distant high-energy universe, but also probe a variety of physics largely inaccessible by other means, including probes of dark matter and non-standard interactions. This talk will describe the current and and near-future cubic-kilometer-scale (and larger) experiments required to detect these neutrinos, including IceCube, P-ONE, and RNO-G, recent results, and the rapidly-multiplying number of questions about this population of PeV-scale neutrinos.
