Pasochoa is an extinct volcano located in the Guayllabamba river basin in the Ecuadorian Andes. The current mountain form is a collapsed crater with a semicircular shape. This structure emerged approximately 100 thousand years ago due to an eruption which destroyed the crater and occidental slope of the previous volcanic cone.
Lava and ash increased the fertility of the ground in the Pasochoa region, encouraging the growth of a vibrant forest ecosystem. Despite the fertile soil, difficult accessibility and an uneven surface made the area inappropriate for extensive agriculture. The Pasochoa Wildlife Refuge, established in 1996, contains one of the few remaining original Andean forests.
