Beneath the multicolored surface lies the land"s history, including the remains of ancient horses, camels, tigers, and rhinos. The barren landscape, dotted with pinnacles and prairies, was formed by two geological processes: deposition, where the layered rocks were gradually stacked up on top of each other by inland seas, winds, and rivers over millions of years, and erosion, which began about 500,000 years ago. The Red Shirt Table, at 3,340 feet, is the highest point in the park, which was established on this day in 1978. It protects 379 square miles of rocky buttes, pinnacles, and prairies. This inhospitable terrain was called "Mako Sica," or "land bad" by the Oglala Lakota people, who have lived here for hundreds of years. Still thirsty for knowledge?

Brown-throated three-toed sloth in cecropia tree, Costa Rica
Costa Rica"s forests are habitats for two sloth species: Hoffmann"s two-toed sloth and the star of today"s homepage, the brown-throated three-toed sloth.

Their large stomachs have four chambers, which, when full, account for about 30% of their body weight. These shaggy critters are so sedentary that algae grow on their coats, which helps to camouflage them within the rainforest canopy. In 2021, these slow-moving creatures were declared national symbols in Costa Rica.
