Exposure: The unit is most famous for forming the wide, greenish “Tonto Platform” in the Grand Canyon, Arizona. It is best viewed along the Bright Angel Trail or the North Kaibab Trail, where it creates a distinct recessive slope between the cliff-forming Tapeats Sandstone below and the Muav Limestone above. Age: Middle Cambrian (approx. 505–515 […]
Exposure: The Tapeats is most spectacularly exposed in the Grand Canyon, Arizona, where it forms the dark, prominent cliff directly above the Inner Gorge. Excellent accessible views are found at the base of the Bright Angel Trail and along the Tonto Trail, where the unit creates a distinct “stair-step” in the canyon’s profile. Age: Early […]
Exposure: Best seen in the Grand Canyon as the top layer of the Tonto Platform (e.g., along the Bright Angel Trail). It also crops out in the Virgin River Gorge of Arizona/Utah and the Frenchman Mountain area near Las Vegas. Age: Middle Cambrian, 505-495 million years ago. Depositional Environment: Primarily a shallow marine carbonate shelf. It […]
Exposure: Prominent throughout the Grand Canyon (e.g., South Kaibab Trail); also visible in the Virgin River Gorge, Pavant Range, and San Rafael Swell. Age: Mississippian, 359-330 million years ago. Depositional Environment: High-energy shallow marine shelf. Specifically, a carbonate platform featuring oolitic shoals, crinoid thickets, and lime-mud flats distal from continental sediment sources. Paleogeography: Located on the […]
Look, I’m not saying the International Commission on Stratigraphy is incompetent—just that they clearly got lazy around 145 million years ago. Every other period in the geologic column has its shite together. Cenozoic? All “-ocene” endings: Eocene, Oligocene, Miocene—like a biglove Utah family reunion where everyone’s name ends in the same vowel sound. Paleozoic? “-ian” […]
Nestled within the Glen Canyon National Recreation Area (GCNRA), Lake Powell is a testament to both human ingenuity and the enduring power of nature. The lake fills the entirety of the roughly…
Hidden in a remote corner of Washington County is a fascinating place nearly forgotten among the other attractions of southern Utah. The scenic Pine Park area exposes intriguing volcanic deposits that reveal the story of the largest volcanic eruptions in Utah’s geologic history.

Exposure: The Supai Group is seen throughout the Grand Canyon. Moving northward it transitions into the Hermosa Group and can be Seen in the Goosenecks area and especially in Canyonlands. Farther north, the time equivalent Weber Sandstone of the Vernal area is particularly notable. Age: Early Permian, 315-285 million years ago. Depositional Environment: deposited in a […]
