In the northwest of South America, the towering peaks of the world's longest continental mountain range give way to an expanse of lowland rainforest. The resulting 5000m elevational gradient is home to the greatest biodiversity on earth. From the seemingly uninhabitable, precipitous slopes of volcanic peaks, to the depths of the Amazon, and everywhere in between, a daunting variety of unique plants and animals can be found.
