Just north of Gill Bridge 21 where
the Gill empties into the Lake is
a
small inlet marked by a large fallen
tree and beyond that tall grass and
weeds. Hidden deep within the
overgrowth in this area that was
once an extension of the Lake is a
sealed cave with its large bedrock
cover seen to the right above.
Created as a port of adventure for
rowers who could leave their boats
to explore the area, it added an
unusual mystique to the Park
experience. When the homeless and
unsavory characters took refuge
there at the turn of the century it
became too dangerous to maintain,
so it was sealed and the inlet was
filled. Yet it remains a Park landmark
and the area is still fun to explore.
