Keystone Canyon

Keystone Canyon is a narrow gorge with nearly vertical slate walls that frame the Lowe River as it flows through the landscape. The steep rock faces line both sides of the canyon, creating a striking natural corridor.

Captain William R. Abercrombie named the canyon in 1898 during his exploration of the region. The name references Pennsylvania and reflects the early role this passage played in regional transportation.

The canyon serves as a connection point for the Trans Alaska Military Packtrain Trail, maintaining its role in transportation through multiple generations.

The location is accessible from the Richardson Highway, where several viewing areas are positioned along the roadside. Visit during clear weather when the waterfalls are most visible and the canyon walls can be fully seen.

During winter months, the waterfalls freeze into substantial ice formations that serve as natural climbing routes. These frozen structures transform the canyon area into a winter climbing destination.
