Gore Canyon

Steep and rugged, the approximately 3-mile-long (4.8 km) gorge was carved by the river as it passed the northern end of the Gore Range southwest of Kremmling.

The canyon is roadless and inaccessible by most traffic, except for the Union Pacific Railroad's Moffat Tunnel Subdivision and whitewater boats.

Despite the short length, the canyon presented a formidable obstacle for the railroad, and the building of the line through it was considered a monumental engineering achievement in its day.

Today, expert kayakers and rafters frequent the canyon, and now even hold a river festival including races and other river celebrations.The Gore Canyon Whitewater Festival is held every year on the third Saturday of August and is also the host of the US National White Water Rafting Championship.

This added to an existing herd to help boost the population after declines due to competition with domestic animals, hunting, and disease.
