  The two-dimensional free-boundary problem describing steady gravity waves
with vorticity on water of finite depth is considered. Under the assumption
that the vorticity is a negative constant whose absolute value is sufficiently
large, we construct a solution with the following properties. The corresponding
flow is unidirectional at infinity and has a solitary wave of elevation as its
upper boundary; under this unidirectional flow, there is a bounded domain
adjacent to the bottom, which surrounds an interior stagnation point and is
divided into two subdomains with opposite directions of flow by a critical
level curve connecting two stagnation points on the bottom.
