  We characterize when the countable power of a Corson compactum has a dense
metrizable subspace and construct consistent examples of Corson compacta whose
countable power does not have a dense metrizable subspace. We also give several
remarks about ccc Corson compacta and, as a byproduct, we obtain a new proof of
Kunen and van Mill's characterization of when a Corson compactum supporting a
strictly positive measure is metrizable.
