Our plateau jutted out the sudden eastern edge of the Andes mountains. It ran east 10 more miles, almost flat, until it dropped over a cliff 2,000 feet into the Amazon Jungle below. Weather from the northeast hit the cliffs first, accelerated upward, then smacked against the massive peaks behind. So, it rained. A lot. Twenty-one feet per year. We called three rainless days a drought—broiling sun and oppressive humidity. Lumbering trucks and packed buses morphed dirt roads into towering billows of fine, choking dust visible from the air as undulating brown ribbons.
