  Clumped dark matter arises naturally within the framwork of generic
cosmological dark matter models. Invoking the existence of dark matter clumps
can also solve may unexplained mysteries in astrophysics and geology or
geophysics, eg. the galactic gamma-ray halo and the periodic terrestrial flood
basalt volcanic episodes. Clumped dark matter is dynamically stable to friction
and will not heat the disk. Such clumps may have already been discovered in the
form of dwarf spheroidals, and further searches are encouraged by the results
of this paper.
