The Rocky Mountain goat is a common sight on Colorado’s highest peaks, with 1,434 records in open occurrence databases, nearly all of them iNaturalist photos from summer visitors. It is also, unlike almost everything else on those summits, not originally from here.
An introduced animal that took hold
Colorado has no native mountain goats. The animals on the state’s fourteeners descend from wildlife-agency transplants that began in the 1940s and 1950s, stock moved in from northern source populations so that hunters and hikers would have a goat to find. Those introduced herds are now self-sustaining and, in places, thriving well beyond their historic range. NatureServe reflects that history by declining to assign a state conservation rank, treating the population as established but exotic rather than part of Colorado’s native fauna.
Where and when to see them
Look on genuinely steep alpine rock: the talus, ledges, and open basins above continuous forest where nothing heavier can follow. Clear Creek and Summit counties dominate the records, and the reason is access. The paved road toward the summit of Mount Blue Sky, long known as Mount Evans, puts drivers face to face with animals that have largely lost their wariness of people. Sightings cluster in the short high-country summer, when the passes are open and salt-hungry goats drift toward parking areas and trailheads. In winter the same animals stay on wind-scoured rock, far from any road.
A field note
Both sexes carry the same slim black horns, so two goats traveling together are usually a nanny with her kid or a pair of females, not a male and a female. The roadside animals near the Mount Blue Sky summit look tame but are wild, pulled toward parked cars by the mineral salt that alpine forage cannot supply.
