Neutrinos with energies above 1016 electronvolts have yet to be detected, but offer great opportunities for discovery, uniquely probing astrophysical sources at the highest energies and greatest distances. I am leading work to develop a new technique - using radar - to detect these neutrinos when they interact in ice. In this talk I will detail our recent, OSU-led test beam experiment at the SLAC National Accelerator Laboratory where our collaboration made the first definitive observation of a radar echo from an electron-beam induced particle cascade. This observation - along with our current efforts toward an in-nature prototype station described here for the first time - may lead to a new neutrino detection technology for energies unreachable by current techniques.
