GeoSight— Wall Arch, a Fallen Giant

During the night of August 4, 2008, Utah lost a popular giant when Wall Arch, a prominent arch along the Devils Garden Trail in Arches National Park, collapsed. While not the largest or most famous arch in the park, Wall Arch was still a favorite due to its proximity to Landscape Arch along the always-busy […]

GeoSight— Fantasy Canyon

Geologic Information: The sandstone layer in which the pinnacles, pillars, arches, and knobs of Fantasy Canyon are formed consists of ancient river channel sediments. The underlying and overlying rock layers sandwiching the sandstone layer, and creating scenic badland topography around the canyon, are finer grained floodplain deposits. During the Eocene Epoch, 55 to 34 million […]

GeoSight— Cascade Springs

Geologic Information: The area around Cascade Springs is underlain by coarse-grained glacial sediment deposited when glaciers covered high elevations of the Wasatch Range approximately 30,000 to 10,000 years ago. Beneath the glacial deposits, bedrock consists of Cambrian-age (about 500 million years old) quartzite, shale, sandstone, and limestone. These rocks were transported eastward 30 to 50 […]

St George 30′ x 60′ 3-D Geologic Map and Virtual Field Trip

Through the use of computers and the Internet, and virtual globes such as Google Earth, we now have a way around the inherent limitations of depicting the third dimension on a standard paper geologic map. To help users gain this 3-D advantage, the UGS created an overlay of the new geologic map of the St. […]

Laying to Rest an OverARCHing Issue

Does Utah have the biggest natural arch in the world? Yes. Sort of. Depends on your definition of “biggest”. Mapping geologists with the Utah Geological Survey recently published an article in the May 2009 edition of Survey Notes that attempts to answer that question. “In nearly three decades of working in Utah’s geology, I have been […]
