Colorful bands of algae and diatoms in the Great Salt Lake, Utah.

The hypersaline lake covers 1,700 square miles but has a maximum depth of about 35 feet. It’s typically 3 to 5 times saltier than the ocean and fish free. The phytoplankton blooms in January followed by several species of diatoms.

The subject of Puzzle 44, this is a photo from the air. For the flickrcaching crew, here is a movie of an “extreme telephoto” zoom into the nearby stadium.

  1. Love the film. It also has an odd illusion at the end where the scene looks like it’s distorting like an inflating surface.

    Whether I just need some fresh air or this is a weird trick of the occipital lobe I’m not sure.

  2. Just like the images I get from the controls of my spaceship!

    That is the zoomest zoom I ever saw!

  3. My view:

    G.S.L = algae will invite you to a non-stop one-way trip to the bottom of the Lake instantly, if you fall in. 😯

    D.S. = the salt doesn´t allow algae to exist, neither will it let you go far down from the surface. 😎

    I wish I had with me the photo of my friend Hernan floating… so funny…

  4. artwitness: the scene looks like it’s distorting like an inflating surface.

    Oh, that’s the curvature of the Earth.

    =) It’s also odd looking given that the bottom half of the picture is under water.

  5. interesting, how good is the crop?
    The highest yield feedstock for biodiesel is hydroponic algae, which can produce 250 times the amount per acre as soybeans.
    US Gallons/acre & Litres/hectare
    Soybean
    40 375
    Rapeseed
    110 1,000
    Mustard
    140 1,300
    Jatropha
    175 1,590
    Palm oil
    650 5,800
    Algae
    10,000 95,000

    1 700 square mile = 1 088 000 acre
    so could Great Salt lake produce 1 088 000 000 00 US Gallons of oil in total for a growing season?
    108 800 000 000 gallon [US, liquid] = 3453 milj barrel [US, liquid] oil
    2521 milj barrel [US, liquid] biodiesel
    as 73% is the oil to fuel ratio
