A short half-mile loop on a boardwalk through a very, very strange area of Death Valley – a bonafide salt marsh in the middle of one of the driest places on earth.
If someone told you that you could drive out to the middle of Death Valley and see fish swimming in a flowing creek, you’d probably think they spent too much time in the sun. But if you traveled to the Salt Creek Trailhead, you could see them for yourself.
During the last Ice Age, Death Valley was covered by an enormous inland freshwater sea called Lake Manly. As the ice receded and the landscape sank, the water dried up – but little pockets of life clung on. At one time, the pupfish swam throughout the entire water basin – but since the climate became more arid they found themselves stuck in various springs and water holes scattered in the desert, and the original species has evolved into ten distinct subspecies.
The Death Valley Pupfish or Salt Creek Pupfish lives only in the briny water of Salt Creek, and if you’re patient and keen-eyed you’ll probably be able to spot them in the creek on this hike.
The hike itself is a very short walk along a boardwalk-trail through the salt-marsh like terrain.
Continue as the boardwalk makes its way through the dense growth of pickleweed and salt grass – two plants that have adapted well to this very harsh and unique environment.
Eventually, the boardwalk splits and ends at a loop – it doesn’t matter which way you go first. Both routes will take you to the spring-fed pools of upper Salt Creek, the only section of this marsh that has water year-round.
If you gaze into the water here, especially during the late winter / early spring, you’re likely to see a ton of tiny pupfish on the creekbed, and a few swimming in the water. This impossibly tiny chain of pools is the only place where pupfish eggs can survive into the next season.
