For those who don't know Carrizal, it is an unusual cave with two streams that converge near its spring entrance. One stream is cool and the other warm.
Around 1980 I dove the sumps at the end of both streams. On the cool side Wayne Russell and I surveyed through three sumps and a couple hundred meters of nice air-filled passage to a fourth sump. I pushed that sump a few meters to where it became impassably low. Maybe it has washed open since then. It would be worth checking soon after the next hurricane passes through. The warm stream sump is sometimes freedove along the right wall to get into a little more air-filled passage. About 40 years ago there was a tragic drowning when someone missed that passage. Continuing underwater past that is a pit. Wayne found a pit but had problems with his ears at depth so I was the first down it. It dropped to -13 m and then the passage turned horizontally into a large, lovely passage. As I recall, I had 60 or 100 m of line in my reel before it ran out. On a later trip, I found some small airbells then the passage rose into air at the base of a breakdown slope. I don't recall why I didn't explore it, and never managed to get back, but someone else (Creature? I don't remember) has since checked it and couldn't find a way on. I believe I wrote this all up with more details and a fresher memory long ago for the AMCS Newsletter. I still have the survey notes if someone wants to resurvey the cave. Wayne planned on having the map redrawn but he died a little later diving in Jacob's Well (look at the back issues of the Texas Caver on the Karst Information Portal for that story).

Has anyone recently tried to push the leads ? How accurate and complete is the map ? What other caves are within hiking distance ? A hot-tub could easily setup, although the water at the entrance is mostly just watered-down bat excrement. Imagine getting the water from the upsteam sump to fill the hot-tub. Camping is secluded and there is shade. I am certain that the Monarch Butterflies refuge there at the spring. My personal opinion is there are too many bats in the cave, and they should go find another nearby cave where they won't contaminate the water source. Imagine the cave cleared of all that dusty guano ? There could be some picturesque photos to take. Imagine a good gate on the cave. Imagine a caver hut outside like at Punkin and Deep. David Locklear
