Hey Elliot! You have great photographs there from your trek. Thank you for sharing them here. What a great way to learn and explore while having fun!

This is my first time to know about sapote. Is its fruit edible? Can the plant be domesticated?

Did Tamarix really caused the draught on the third photo? That's horrible.

The cliff is white because of seabirds’ droppings (“guano”)

That's interesting. I did not realize that bird wastes can cause such huge reaction.

It is sad to see those solid wastes in the middle of nowhere. Those even seem non-biodegrable. I wonder how they got in there.

Cerro Blanco seems an arid land. Is it because it's summer season there or is it because it is really a dry land? It even look like a desert to me...
