Darwin Creek is one of the four perennial streams in three million-acre (12,000 km²) Death Valley National Park. Darwin Falls and Creek are fed by the Darwin Wash, which is in turn fed by the volcanic tableland of the Darwin Bench between the Inyo Mountains and the Argus Range. The small, narrow valley where the creek and falls are located features a rare collection of riparian greenery in the vast desert and is home to indigenous fauna such as quail. The falls themselves support several small fern gullys.
