Day 4: Into the Belly of the Earth

So I know the title is pretty dramatic, but then again, it was a pretty dramatic sort of day. It started off uneventfully. I woke up a little later than usual but made it to breakfast on time, just before we had another meeting about today’s project: pee traps! As in, we peed in test tubes and used the urine samples to set pitfall traps for insects. Our urine has a lot of nitrogen in it, so the basic idea is that the nitrogen will attract insects that we will then fish out of our pee pee in a couple of days, all in the name of science.

DeLiciOUs!!

The hike this morning was mostly uneventful. There were the standard blue morphos that flew by, close enough for me to see but not to touch. It’s fine, I’m very much used to those butterflies flying circles around me by now. BUT I AM DETERMINED. I WILL CATCH ONE BY THE TIME WE LEAVE THIS FOREST!! I did, however, manage to catch 3 more butterflies and two moths today, so I’m  sharpening my skills. One of the moths was beautiful yellow and black, and it was a rare diurnal moth! Again, I found all the Lepidopterans flitting near the road on low foliage.

By far the coolest spot of the morning was a coral snake that Sam found under a rotten log – one of the most venomous snakes of Central America. It was smaller than I expected, and very shy. It slithered away almost as soon as we could spot it.

After lunch, we went to hell.

Not really, but it sure did look like it. We entered a cave near Las Cuevas that is not only home to all sorts of creepy cave fauna, but also remnants of the ancient Maya civilization. The black maw of the cave loomed up suddenly over the forest path. Its entrance was filled with hanging stalactites that looked like fangs and cave swallows that nest between them. The Mayans believed this cave to be the entrance to the underworld, and it sure looked the part. We entered via ancient steps carved by the Maya and slowly made our way through the bat poop (guano)-covered cave. I thought the squelchy brown substance spread all over the cave floor was mud, but it was not long before I noticed that it was actually guano. Delicious. Not a single one of us made it out without being covered in the stuff, except maybe our incredible guide, Pedro.

There were definitely some scary moments in the cave involving uncomfortably narrow passages and slippery footing. In some of the most claustrophobic recesses of the cave, I became supremely aware of just how deep I was in the Earth: only alien creatures that are adapted to life in utter darkness can exist here, and I am nothing but an intruder who would stand no chance if my headlamp goes out. It was a humbling and freakish experience that I am glad to have had, but that I am not sure I would repeat. Emerging from the cave was like being reborn.

Goodnight for now! I’ll be up again in too few hours.
