Black Rock Lake

Greg Martin wades out into the ephemeral Black Rock Lake that fills Nevada's Black Rock Desert every spring. Snowmelt rushes down and spreads water across the normally parched desert floor, releasing tens of millions of prehistoric triops longicaudatus ("tadpole shrimp"). These living fossils hatch from eggs which can lie dormant in the alkaline playa for up to 20 years, and provide local birds with a feast.
