Nature can do quite unusual things, like turn a pond in Hawaii bright pink. Maui residents noticed that Kealia Pond had turned a pink and purple hue but were unsure as to the reason.
According to the U.S. Fish and Wildlife Service, the color change was believed to be the result of halobacteria found in waters with high salinity. The pond’s salt content had recently gone undiluted by rain because of drought conditions the area was experiencing, which could explain the bright hues.
Travis Morrin, a photographer from the area, captured some incredible drone footage of the unusual sight and posted it online. “I just happened to drive by and I was like, ‘It’s like Pepto Bismol pink,'” Morrin said.
Officials said the water had turned pink near the end of October and confirmed that it shouldn’t be toxic. Samples were taken and have since been sent to the University of Hawaii for further testing.
