Abstract
Many high-velocity H I clouds (HVCs) are now believed to be scattered throughout the Galactic halo on scales of tens of kiloparsecs. Some of these clouds appear to contain substantial H I masses (> 10(6) M.). It has been suggested that these structures may be associated with dark matter "minihalos"accreting onto the Galactic halo. For a compact HVC along the sight line to a more distant galaxy, we demonstrate that "pixel gravitational lensing" provides a crucial test for the presence of a dark halo in the form of massive compact objects. The detection of pixel lensing will provide an independent means of mapping the mass distribution within HVCs.
