That could also been a concentration of red colored sediment of billions of dead, red skinned Artemia Salina, or brine shrimps.
Artemias have pigmented micro-organisms encapsulated in their tiny bodies which are at the most just 1 cm long.
They have thin dark red colored shells, and those shells appear red when killed during evaporation from brine, of last remains of water out of sunlit
shallow salty ponds.
They can breed explosively in the right circumstances and the water then appears to "wriggle".
In water that contains less than 80% salt, artemias will breed through eggs, but in saltier water they breed viviparous.
Their eggs are so strongly protected against drying up, that they hold their potential for life in years of drought, but will germinate as soon as the
rain inundates the dried up salt flats again.
Flocks of flamingos feeding in shallow brine lakes where these organisms occur in the billions, will develop beautiful pink and red colored feathers.
Artemia is used in private and zoo's seawater aquariums to feed the inhabitants, since their tiny dried eggs can be frozen for a very long period in
the freezer. These preserved eggs will develop in a few days to massive amounts of living Artemia when dissolved in fresh seawater.
In salt winning flats, operating by evaporation of shallow seawater, artemias do play an important role in the precipitation of gypsum from the
seawater in the shallow salt flats.
Some links with funny and interesting info:
Great Salt Lake Brine Shrimp:
A tad bit more scientific explanation, and as you should know, these creatures have been used by NASA and the Russian space program to determine the
effects of ultraviolet radiation on living cells in space:
I wouldn't be surprised if those concentrations of lighter red dots at the north west corner of that lake, and down south of that land-tongue are in
fact migrating flamingos feasting on artemias :
In that case, no stars needed for bloodthirsty ideas or dreams.
