Abstract: Many models of dark matter predict the formation of extremely heavy composite particles in the early universe, with masses well in excess of 10^20 GeV. Today, the fluxes of these particles would be too low to be detectable in direct detection experiments on human timescales. This motivates searches for dark matter signatures in minerals with billion-year lifetimes. I discuss prior searches and future prospects for detecting heavy dark matter both in plastic etch detectors and in muscovite mica.
