Castle Rock cave is located in the southwest region of the
State of Wisconsin. There are not many
caves out here in this region but
Castle Rock cave is not only a limestone cave
it is a spring resurgence that is completely submerged underwater. We completed
our training dives in nearby submerged mines for our Full cave certification so
Tamara Thompson took us over for a unique experience.

Tammi taught us how to
utilize our diving equipment in a no mount configuration so we are able to push
our tanks ahead of us in tight restrictive passages in order to continue
exploration. The cave entrance was really small and we could only crawl into
the entrance with surging water pressure evacuating from inside of the cave

We donned our wetsuits so we would rip our dry suits by
going through the tight squeezes within the cave.

The water was around 52 degrees F and we
strapped two AL 80s to each other along with extra lights to the center counsel
of the no mount configuration. Inside the cave, there were varnished walls and
some sign of phreatic erosion on the walls.

Eventually we made it to the “cheese grater” which is a
particularly narrow section where all of our gear was dragging between the
ceiling and the floor of the cave.
It
was a rather tight squeeze but the clear visibility of the water made the push
a bit easier, though when we would go through a plume of silt would kick up and
turn our visibility to zero.

Luckly, we
had a lot of flow which would clear away the silt and bring our visibility back
to a very clear condition.

We wanted to
continue exploration but not only did we find the local muskrats ate away at
the dive line, we were reaching our thirds so we turned our dive back to the entrance.

We came back out and entered the cave again to lay some more
line and that’s when I felt something run right over my back, it was a
muskrat! There is a family of muskrats
living inside of an airbell within this cave.
We understand that this cave is around 550ft in total length and there
is a dry section up in the hill that might connect to the cave one day. We are grateful that we got to learn how to
no mount dive and I am sure it will come in handy with future explorations.
