Local residents and landowners have nicknamed this site "Valley-of-the-Moon" because it appears as a barren landscape at first glance. Large wind-swept alkali lakes are surrounded by barren, salt-encrusted beaches and large glacial boulders. Native prairie on the preserve is strewn with salt-tolerant plant species and in some places, only the hardy salt grass can prod its way through the hard gravelly substrate adjacent to the lakes.

The most significant feature of John E. Williams Nature Preserve is its breeding population of piping plovers. The federally threatened shorebird finds the barren shoreline ideal nesting habitat and the abundant crustaceans a vital food source for adults and young chicks. In fact, this area harbors one, if not the largest concentration of breeding piping plovers in the world.

Expect to see piping plovers in May, June, and July. Other bird life, including a diversity of many duck species, raucous marbled godwits, and dainty phalaropes are also readily seen. Fall and spring conditions attract thousands of unusual shorebirds and waterfowl, including cranes, geese, and swans.

Facilities: None.
