# Hornopirén National Park

Hornopirén National Park (Spanish pronunciation:) is located in the Andes, in the Palena Province of Chile's Los Lagos Region, also known as Region X. The park contains 482 km$^2$ (186 sq mi) of rugged mountains and unspoiled Valdivian temperate rain forests. This national park borders the northern portion of Pumalín Park. The Carretera Austral passes close to the park. In the vicinity of the park lie Hornopirén and Yate volcanoes.

## Geography

The park is part of the Andes mountain chain. There are 22 hectares of mountains, glaciers and volcanoes. The park is dominated by glacier-carved mountains and active volcanoes. It includes glaciers comprising an area of 30 km$^2$ (12 sq mi). The Yate volcano stands 2,187 meters above sea level and the Hornopirén volcano stands 1,572 meters above sea level. From the Yate volcano southern slope, at only 1,500 meters, you can enjoy panoramic views of the mountains and forests of the park, including a full view of the lake and even Pinto Concha Hornopirén fjord.

## Water

The three main bodies of water in the park are Pinto Concha Lake 4.75 km$^2$ (2 sq mi), Cabrera Lake 1.55 km$^2$ (1 sq mi) and Inexplorado Lake 1.5 km$^2$ (1 sq mi). Pinto Concha is the most visited attraction in the park. There are six main rivers in the park. Inexplorado Lake is one of a series of paternoster lakes that form part of the Blanco River drainage basin. The aforesaid lakes are characterized by distinctive blue and green hues, due to rock flour suspended in their waters and give to the river its milky appearance. Negro River is another major river system in the park.

## Forests

They are surrounded totally or partially by millennial alerce also known as larch forests. The Alerce tree is the second oldest tree species on the planet. It includes Fitzroya trees almost in pure stands. The pristine alerce forests cover an area of about 97.41 km$^2$ (38 sq mi), which comprises approximately the 35 percent of the vegetation cover of the park.

## Biology

The park has about 25 mammal species, including native as well as exotic species. Among them are the cougar, kodkod, lesser grison, chilla fox, American mink, coypu, pudú and Chilean huemul. The park is home to 18 threatened species.
