2 Best Sights in Spokane and Eastern Washington, Washington

Claw-shape, 38-foot-deep, 18-mile-long Moses Lake is filled by Crab Creek—which originates in the hills west of Spokane—with three side branches known as Parker Horn, Lewis Horn, and Pelican Horn. The city of Moses Lake sprawls over the peninsulas formed by these "horns," and can therefore be a bit difficult to get around. This is the state's second-largest lake.

The water is high in dissolved carbonates, sulfates, and chlorides, and the lake has long been famous for its mineral waters and therapeutic mud baths; in fact it was called the "World's Greatest Medical Marvel" more than a century ago. Yet the eponymous small town has never quite succeeded as a modern-day resort—perhaps because the miraculous waters have been heavily diluted by irrigation waters. Still, a loyal contingent of believers return to the lakeshore each year to cover themselves in the mud that they find healing.
