  Given any compact hyperbolic surface $M$, and a closed geodesic on $M$, we
construct of a sequence of quasimodes on $M$ whose microlocal lifts concentrate
positive mass on the geodesic. Thus, the Quantum Unique Ergodicity (QUE)
property does not hold for these quasimodes. This is analogous to a
construction of Faure-Nonnenmacher-De Bi\`evre in the context of quantized cat
maps, and lends credence to the suggestion that large multiplicities play a
role in the known failure of QUE for certain "toy models" of quantum chaos. We
moreover conjecture a precise threshold for the order of quasimodes needed for
QUE to hold--- the result of the present paper shows that this conjecture, if
true, is sharp.
