An unprepossessing storage reservoir in southern Utah has a checkered past.

When it was built in 1929, this historic bridge was the only place to cross the Colorado River for 600 miles.

A sharp bend in a dramatic river canyon cut through red rocks.

This isolated outpost was once the only place to cross the Colorado River for hundreds of miles.

The remains of this early 20th century refinery loom on a mountainside like a graffiti-covered fortress.

Only ruined buildings and abandoned charcoal kilns remain of this once bustling Wild West boom town.

A shady solar power system that couldn't hold up to the harsh desert conditions.

This lonely gas station has stood at this location since 1917.
