Although it's the dry season in this region of Ecuador, we experienced heavy rains and strong currents on the Nagaritza as well as spectacular waterfalls along our route.
After embarking on the 3 hour hike to the cave, the peril became more perilous.
Conga Ants, or "48 hour" ants are over an inch long and bite hard enough to leave you in pain for several days. I took the picture - the guide chopped it in half.
My previous trip to Ecuador brought us in contact with venomous centipedes, so when I came across this cartoonish looking beast I declined to hold it, despite our guides willingness to do so. He did - he survived - I still didn't trust him. In case you're wondering - Centipedes have 2 sets of legs per segment. Millipedes 4 sets.

After 3 hours of hiking through the rain forest, we arrived at Tayos Cave, named for the nocturnal birds that roost within. With headlamps on - our party of six descended from the glowing green canopy of the jungle into the muddy, damp darkness.
The cave was made famous in the 60's by Argentinian entrepreneur Janos Moricz whose expedition in 1969 supposedly discovered a vast series of tunnels and a "Metal Library". The wild claims drew much attention and in 1975 a scientific exploration set out to settle the claims, bringing along an honorary member of the team, Neil Armstrong. The metal library was never found although there are some interesting limestone formations. What we did find were the Tayos birds or Oilbirds that locals harvest. Just before fledgling, the birds gain a considerable amount of weight. Locals climb bamboo ladders to the cave ceiling where they extract the chicks from the nests and render their fat for oil.
The birds don't respond well to these disturbances in their cave as you can imagine and screech out a noise in the darkness that sounds not unlike the Predator from Arnold Schwarzenegger's movie of the same name. Later tonight, turn out all the lights and play this clip of Oilbirds to simulate the effect.

I could have sworn I had good batteries. They had been working fine, but my light - which was also Ma-Le's illumination died at quite the inopportune time. Half way into the cave as we carefully stepped back and forth across the cave stream and just as we were ducking under a large boulder and squeezing through a narrow passage with just one more step to reach the plateau - darkness.
I can imagine how the Neil Armstrong expedition in 1975 would have gone.
"That's one more small step..."
"Holy crap what was that!"
Look at the face on that thing! It's just as terrified as Ma-Le! But it does look familiar....

As we left the cave, the Belgians left us behind again to grope the rock walls and slosh through the stream in darkness - eventually emerging back into the rain forest. Why couldn't they wait!
I guess I shouldn't have made that Belgian Waffle joke the night before. But it was a good one.
