Standout amethyst 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.
Marysville
Piute County County
Marysvale earns a top spot for small but well-formed crystals in rhyolite cavities, especially bixbyite, amethyst, and reported rutile or pseudobrookite. UGS describes the occurrence as BLM public land in a mid-Tertiary volcanic field, and Mindat records the same locality north of Marysvale with bixbyite, amethyst, pseudobrookite, and rutile.
