CASTLE ROCK CAVE DIVE

This cave is located in the southwest side of Wisconsin and it was a real treat to visit! We completed our training for the day and went to a cave with a large flow of clear water surging out of the entrance.  We put on our wetsuits due to the tight spaces this cave offered as we didnt want to ruin our drysuits plus the water was warm enough to to deal with the water temp.
THE ENTRANCE TO CASTLE ROCK CAVE

We entered the cave passage and I was amazed to see how clear the water was even with all the snow melt going in the region.  The passag itself was rather small which made this dive a "no-mount" dive.  We had to strap two AL 80's to cam bands and strapped on essentials for this dive so we can push the tanks ahead of us in order to proceed through the passage.  I also enjoyed how the colors of a cream limestone blended in the clear blue tint the crystal clear water created.  Also dark features varnished the passage walls and rock which ate up a lot of light but gave the cave a lot of charter

INSIDE THE CAVE PUSHING TANKS THROUGH THE UNDERWATER PASSAGE

We got to the "cheese grater" restriction which was a bit more of a push and small drag through a tight section that popped out into a place where you could actually sit down and wait for you buddy.  We wanted to continnue to push the cave but the mainline was broken as the Muskrats have bit through the line, AGAIN.  We decided to turn the dive since we were nearing our thirds and the line was broken so we were not sure which section to pursue.

THE PASSAGE RIGHT BEFORE THE "CHEESE GRATER"

We turned our dive and made it out of the cave and realized how wonderful that cave was to be in so with the amount of gas we had in reserves we entered the cave once more to check out the entrance side passages.  I was laying down the main line when I felt something run across my back, thinking it was just a bunch of bubbles I ignored it until I saw a muskrat swimming around the passage wall.  The coat had this shimmer and when we briefly made eye contact, the Muskrat took off swimming to a section inside the cave with low air where a family of Muskrats live.  It was a beautiful moment.  We continued to make a brief entrance and exited the cave.  Once we were de briefing My dive buddy and I decided we want to come back and push to the end of the cave which is only 550 ft and has a sand hill that wedges into the wall.
