Black Rock: Before and After

Friends of Nevada Wilderness joined other conservation organizations to build a fence around sensitive habitat on the Black Rock playa to celebrate National Public Lands Day. Most sand dunes are formed when loose sand is windblown into an obstacle, forming a mound. However, the dunes on the Black Rock playa indicate springs below the surface. The water pushes the sediment upwards, forming a dune and creating a habitat for desert plants and wildlife.

Irresponsible off-highway vehicles driving through the area have began to slowly destroy the dunes. Volunteers worked a long, hot Saturday in the sun to build a fence around the area to prevent off-roading in the habitat.
