Salk Creek Death Valley is the only place in the world
where the Salk Creek Pupfish live. Some 20.000 years ago when Death Valley
was a big fresh water lake there were probably many species of fish that
lived here but today only the pupfish remain. The pupfish managed to adapt
to the harsh environment related to life in the desert. For example the
pupfish is well adapted to high salinity, they can survive in water 2 to 3
times saltier than sea water. You can see the pupfish by walking the 1/2
miles boardwalk which passes through the salk creek. The creek almost dries
up in the summer and only a few pools of water remain. Only those fish in
deeper pools survive. There were quite a few pupfish visible when we visited,
in mid February.
