Vulcan's ThroneAbout Vulcan's Throne
Vulcan’s Throne is a volcanic cinder cone located on the North Rim of the Grand Canyon in northwestern Arizona. It forms part of the Uinkaret volcanic field and rises at the canyon rim above the Colorado River.
The cone was produced by relatively recent volcanic activity within the Uinkaret field; lava flows from vents in this field reached the canyon floor in multiple episodes. Those flows altered local river morphology where they reached the Colorado River.
The feature sits on the Grand Canyon’s North Rim near the Toroweap/Tuweep area in northwestern Arizona. The location is remote with limited nearby services; approach is normally via unpaved roads from the north or east.
- Geology: The site is a cinder cone on the North Rim of the Grand Canyon and is part of the broader Uinkaret volcanic field.
- Access: Access is remote and typically via the unpaved Tuweep/Toroweap road; high-clearance vehicles and planning for limited services are strongly recommended.
