Defiance is a steel roller coaster currently under construction at Glenwood Caverns Adventure Park in Glenwood Springs, Colorado, USA. It is set to open in 2022.



In April 2021, it was announced that Gerstlauer had signed an agreement to construct a "record-breaking" roller coaster in the United States.[1]

Defiance at Glenwood Caverns Adventure Park was announced on August 5, 2021 via an exclusive story in USA Today.[2] A groundbreaking ceremony was held on August 20.[3]

The first track pieces arrived in the spring of 2022.[4] Vertical construction had already started by May 2022.[5]

The final piece of track was installed in June 2022.[6]


Unlike some other roller coasters with beyond-vertical drops, there will be no brakes during the drop. The coaster is claimed to have the "steepest drop in the Western U.S." at 102.3. While Cannibal at Lagoon has a steeper drop at 116 degrees, it has brakes during its drop.[2]
