Where to Find Carnotite in Utah
Carnotite is the lemon-yellow uranium-vanadium ore mineral that drove Utah's uranium boom of the 1950s. Most occurrences are in the Salt Wash member of the Morrison Formation, with concentrations in the Uravan mineral belt extending into San Juan and Grand counties. The Lisbon Valley, White Canyon, and Henry Mountains districts produced carnotite as powdery coatings, channel-fill ore, and replacements after fossilized wood. The Cane Creek anticline near Moab carries carnotite alongside copper minerals in sandstone. Carnotite is radioactive, and specimens should be stored ventilated and never displayed in a closed living space. A Geiger counter is useful for both finding and grading material.

Standout carnotite spots in Utah
Hand-picked from the full list below, with the reason each one earns a trip.
San Rafael Swell
Emery County County
The San Rafael Swell is a broad exposed anticline where Morrison, Curtis, and Cedar Mountain strata carry local agate, jasper, chalcedony, petrified wood, and dinosaur-bone material. BLM manages the Swell as a major public recreation area, and UGS describes the same formations as part of the area's collectible rock and mineral resource base.
Spor Mountain
Juab County County
Spor Mountain stands out because its topaz-rhyolite-related deposits made it the world's premier beryllium district and Utah's largest fluorite producer. Mindat documents bertrandite, fluorite, chalcedony, opal, carnotite, hematite, magnetite, pyrite, quartz, and topaz across the district, which makes it more than a single-specimen stop.
Topaz Dome Quarry
Juab County County
Topaz Mountain is Utah's defining gem locality, where amber topaz crystals formed in cavities of the Topaz Mountain Rhyolite and commonly bleach colorless in sunlight. The BLM identifies the area as a public rockhound recreation site, while the Utah Geological Survey documents topaz, red beryl, amethyst, garnet, bixbyite, opal, and hematite in the same volcanic field.
