This is Lake Atitlan Guatemala. 13 villages around its shoreline. It is an 82 mile wide crater lake. there is no outlet...on rivers and steams going in. its depths can not be measured because of caverns. i have heard people say things like this lake is connected to other deep crater lakes like it... through underground channels that work like the deep veins of the planet. but lots of people say a lot of crazy shit down here.
