The National Park of Tikal, Guatemala — Hidden within the heart of the Guatemalan rainforest, a 2,800 year old city was once home to nearly 100,000 Mayans. Today, the jungle has returned. Cries of howler monkeys pierce the dawn, while colorful parrots and toucans soar from branch to ancient temple. From atop the Lost World Pyramid, we see the red sun break the morning mists. This site once charted the solstices and planting seasons, and was accessed exclusively by the priests and the social elite. Each day's return of the sun was seen as a rebirth of the sun god Kinich Ahua. On this morning, we witness the magnificence of a lost human world and the ongoing life force of the Central American rainforest.
