Rock With A Face - Goblin Valley, Utah
The Jurassic Entrada Sandstone in Goblin Valley erodes into Hoo-doos; a geologic feature formed as a result of multiple layers of less erosionally resistant sands which were deposited within more erosionally resistant sands that, combined with rain and wind, create the unique pattern of erosion seen here.

Mineral deposits in Lechuguilla Cave take on fantastical forms in Carlsbad Caverns National Park, New Mexico. Stalactites of calcite and a small aragonite formation appear as if in a magical backdrop. Their crystal structure sets them apart: calcite forms hexagons and aragonite forms rhombohedrons.

A volcano in Java, Indonesia, produces yellow deposits of sulfur that prove to be easy but dangerous pickings for a man collecting the mineral. Sulfur often combines into sulfides or sulfates. The nonmetallic element heals and destroys: Doctors use sulfur to treat fungal infections, but it is also a component of gunpowder. Sulfuric acid is an important industrial agent.
Azurite crystals from Arizona seem to pulse with color. The mineral azurite—a copper ore—consists of blue basic carbonate. Azurite’s brilliant color adds to its popularity in creating semiprecious stones.
