Some of the most enigmatic phenomena in the Universe -- black-hole driven Active Galactic Nuclei, pulsar-driven Supernova Remnants, and perhaps even Gamma-Ray Bursts -- are now known to be strong gamma-ray emitters. Many have been seen and studied from orbiting satellite-based detectors, and a few from the ground. Unfortunately, these two techniques have, until now, left an 'unexplored window' in gamma-ray energy between approximately 10 GeV and 250 GeV. There is good reason to expect that this energy range is crucial to understanding these sources and the propagation of gamma-rays across the Universe. A number of new techniques and detectors are addressing this energy range; this talk will briefly introduce the scientific motivation for these detectors and talk about the different experimental approaches.
