Abstract: I describe a dark matter candidate based in qcd physics in which the darkmatter is composed of macroscopically large -nuggets- of quark and anti-quarkmatter. These objects may have a sufficiently massive low number density toavoid constraints from direct detection searches. Though not -baryonic- in theconventional sense quark matter is strongly interacting and will produce aclear signal in ground based detectors. As the prospects of detecting theseobjects are mainly limited by the detector cross-section large scale cosmic raydetectors are a promising search platform. To this end I describe the basicproperties of the air shower induced by the passage of a quark nugget throughthe earth-s atmosphere. It will be shown that this shower is similar in severalimportant ways to the shower induced by a single ultrahigh energy cosmic ray.
