1. Laguna Colorada: A Surreal Red Lake in Bolivia
Advertisement
Tucked in the high-altitude deserts of southern Bolivia, Laguna Colorada is evidence of how creatively nature can produce fantastical settings. With its unique orange-red waters that seem to defy reality, this roughly six-mile-wide salt lake enthrals tourists. Still, the lake's present scale is barely a fraction of its past splendour. Ancient shorelines carved into the surrounding terrain expose a history of a far greater body of water, suggesting the enormous geological changes over millennia that have moulded this area.
The lake's captivating colour comes from a natural occurrence brought on by red algae flourishing in its waters, not from pollution or artificial colouring. Adapted to the particular chemical makeup of the lake, these microscopic creatures provide the distinctive red tint that has made Laguna Colorada famous. Fascinatingly, the lake's look is not fixed; sometimes it changes remarkably to become a brilliant green. Usually brought on by changes in water temperature and salinity, this colour change results from environmental factors favouring the growth of another type of algae.
Laguna Colorada is more than just a visual feast; it's also a vital habitat for several species, most famously the James's flamingos. These graceful birds, with their pink plumage, find perfect habitat in the shallow waters of the lake. The flamingos create a lovely symbiosis with their odd habitat since they eat the very algae causing the colour of the lake. A photographer's dream and a potent reminder of the complex balance of nature, the sight of hundreds of flamingos wading over the red waters reflects on the lake's surface.
The islands of sparkling white that dot Laguna Colorada's red expanse add to its unearthly look. These are borax deposits—a mineral compound left behind by saltwater's evaporation—not sandy beaches or limestone structures. Further accentuating the lake's alien-like look is the visually arresting pattern created by the sharp contrast between the white borax islands and the red water. These borax sites offer not only aesthetic appeal but also reveal information about the geological processes of the lake and the mineral-rich surroundings.
Laguna Colorada's special qualities have made it a popular spot for both environmentalists and researchers. Its place inside the Eduardo Avaroa Andean Fauna National Reserve guarantees some degree of preservation for this delicate habitat. But the site's growing popularity also begs questions about how human activity may affect this delicate ecosystem. Constant efforts are being made to strike a balance between the necessity to protect this natural beauty for next generations and the want for access to it.
