This is actually a picture I took from a recent family trip to Peru. Then as you get right onto the coast, it will be pretty arid desert. And then when you get up into the mountains, they're fairly high altitude, you'll have these mountain valleys that are, some of them are at 7,000, 8,000, 9,000 feet. This is actually another picture that I took from my recent family vacation in Peru a few months ago. And what's interesting about the ancient civilizations there is some of them might have settled on the coast to take advantage of the fishing that was available. There were some rivers, or there continue to be some rivers that go from the mountains through the desert. So some early agriculture developed around that.
