  We present subarcsecond images of submillimeter CO and continuum emission
from a local galaxy forming massive star clusters: the blue compact dwarf
galaxy II Zw 40. At $\sim$0.4" resolution (20 pc), the CO(3-2), CO(1-0), 3mm
and 870${\mu}$m continuum maps illustrate star formation on the scales of
individual molecular clouds. Dust contributes about a third of the 870${\mu}$m
continuum emission, with free-free accounting for the rest. On these scales,
there is not a good correspondence between gas, dust, and free-free emission.
Dust continuum is enhanced toward the star-forming region as compared to the CO
emission. We suggest that an unexpectedly low and spatially variable
gas-to-dust ratio is the result of massive clusters of the starburst.
