The northern viscacha is native to central and southern Peru and northern Chile, and may also be present in the area around Lake Titicaca in Peru and Bolivia. It is typically found between the timber and the snow lines in the Andes Mountains at elevations between 3,000 to 5,000 meters -- or 10,000 feet to 16,000 feet -- it makes its home in crevices in the rock and is found in various habitats where suitable rocky outcrops are found.

The northern viscacha is a herbivore and feeds on a variety of plant material, including grasses, roots, and seeds.

It grows to a head and body length of some 300 to 450 mm (12 to 18 in) with a bushy tail nearly as long which can be curled in a coil. The adult weight is between 900 and 1,600 g (32 and 56 oz). Its long ears are furry and its body fur is dense and soft, but the tail has coarser hairs.
