Abandoned burrow with scorpion

It is possible to spot the scorpion hiding in what I guess to be the abandoned burrow of a tarantula. It's in the dark spot at the "bottom" part of the burrow. The burrow was covered by a piece of volcanic rock, which was restored into its original place after I took this picture.

And don't worry if you can't find the scorpion, the other two pictures in this gallery show it very well, but I wanted to add this picture because it gives a nice overview of what one can expect under a piece of volcanic rock when walking close to El Lim? Totalco.
