  It is well known that general relativity does not admit gravitational geons
that are stationary, asymptotically flat, singularity free and topologically
trivial. However, it is likely that general relativity will receive corrections
at large curvatures and the modified field equations may admit solutions
corresponding to this type of geon. If geons are produced in the early universe
and survive until today they could account for some of the dark matter that has
been "observed" in galaxies and galactic clusters.
  In this paper I consider gravitational geons in 1+1 dimensional theories of
gravity. I show that the Jackiw-Teitelboim theory with corrections proportional
to $R^2$ and $\Box R$ admits gravitational geons. I also show that
gravitational geons exist in a class of theories that includes Lagrangians
proportional to $R^{2/3}$.
