  The electroproduction of rho mesons is studied at HERA with the H1 detector
at high Q^2 and high |t|. Cross sections are measured as a function of Q^2, W
and t. The W dependence of the gamma*-p cross section is observed to increase
with Q^2 from values compatible with soft Pomeron exchange at low Q^2 to a hard
dependence at large Q^2. Spin density matrix elements are measured and their
dependence is compared with a two gluon exchange model.
