A bixbyite-amethyst-pseudobrookite-rutile(?) occurrence located N and W of Marysvale in the Tushar Mountains.

Travel 2.8 miles north on Center Street in Marysvale on US Route 89. As you begin to enter Sevier Canyon, look for an unmarked gravel road (exactly at 2.8 miles) and turn left (west). Continue approximately 300 hundred yards where you can park alongside the gravel road.

One of the common units found near Marysvale is a white to dark gray rhyolite with extremely well-developed flow banding. The crystals, which are found in cavities in the rhyolite, formed in gas pockets that were trapped in the lava flow as it cooled.

Bixbyite, a rare iron-manganese oxide, occurs as black, metallic, euhedral crystals up to 3/8 of an inch across. The crystals are generally complex combinations of various isometric forms including cubes, octahedrons, and dodecahedrons.

Rutile(?) and pseudobrookite are less common and appear as needle-like or bladed crystals up to 1/4 inch long.

The amethyst crystals, ranging up to 1 inch in length, display excellent crystal form in various shades of purple.
