Another pic of a northern Blind Fish Amblyopsis Spelaea |
The northern cavefish (Amblyopsis Spelaea) is found through out south indiana and Kentucky as a threatened species so special care must be taken to ensure these species are not effected in their natural habitats. We also encountered troglobite crayfish and a few troglophile crayfish and frogs.

We continued down the river passage and we found sections where we had to start swimming to get to the next cut bank around the bend of the river cave. It was quite fun as we were in wetsuits which took the bite off the coldwater. I donned my dive mask and snorkel to see if I could get some close ups of the blind fish and I was able to get a few good shots of them along with a shot of a crayfish and a blind fish next to each other (shown above).

We continued on down the passage and encounterd a large room which I attempted to take pictures of but my camera started fogging up so I wasn't able to get the best shots of the passage.

We found a trail marker in the middle of the ceiling and I wasn't sure if this was the actual border of the property or not so we turned around to make sure we didn't violate any rules. We headed back and took our time to enjoy the fact that we are swimming inside of a cave and it was an easy pace to enjoy.

We went into the upstream section and quickly found a breakdown pile to negociate. We found a tight section to fit through which might have been the way to continue up the passage but we decided not to rip up our wetsuits and return to the entrance. I want to thank Chris Parks for the hospitality and for not smelling like a wet turtle :) you are a good friend and I appreciate you chris. I also want to thank Jesse, Danyele, Jerry, and Tymme for helping to create a nice and safe weekend. We will see you guys soon!
