Kolob Canyon may be off the beaten path, but remains a fan favorite when visiting Zion National Park. Did you know that it also displays some of the park’s oldest geology? Tyler Knudsen, one of our geologists here at the Utah Geological Survey, talks about the geology present in Kolob Canyon in this video. Check it out!
Good 4 Utah is celebrating Utah’s diverse and unique geologic history this summer. Kylie Bearse and photographer Gus Seashore are traveling to Utah’s famous landmarks, and a few spots you may not have known about, to learn more about our state’s geology.

Jurassic-age Navajo Sandstone forms the massive red cliffs of the often-overlooked Kolob Canyons area of Zion National Park. Hanging valleys are present where relatively small tributary streams have eroded downward at a slower rate than the larger trunk stream.
A new geologic-hazards investigation, published by the Utah Geological Survey, could help Zion National Park (ZNP) keep its 2.5 million annual visitors safe. The results of the investigation will provide the National Park Service (NPS) with geologic-hazard information for future park management.
Zion National Park is subject to a variety of geologic hazards that may affect park development and visitor safety. “One of the nation’s scenic jewels, Zion National Park, is also home to a variety of geologic hazards. By supporting this study of geologic hazards in high-use areas of the park, the National Park Service has taken a proactive approach to protecting visitor safety,” says William Lund, UGS Senior Geologist.
The ZNP geologic-hazards study area is a 154-square-mile area that encompasses Zion Canyon, Kolob Canyon, Kolob Terrace, the Zion-Mount Carmel Highway corridor, and all developed and high-use areas of the park. This investigation includes nine 1:24,000-scale geographic information system (GIS)-based maps that show areas subject to flooding, debris flows, rock fall, landslides, surface faulting, liquefaction, collapsible and expansive rocks and soils, and/or soil piping and erosion.
