In the rainforest of Costa Rica, wildlife photographer David Weiller captured beautifully drone footage of a shimmering clear bright turquoise blue waterfall that splashed down from a lush green mountain high above.
Winding through the rainforest of Costa Rica, these bright blue waterfalls and rivers make one feel as if this was a fairy tale.
This beautiful color is due to the scattering of large aluminosilicate particles, known as Mie, that reflect the blue light of the spectrum.
The rivers upstream are not blue and they contain a large concentration of whitish mineral particles known as aluminosilicate (composed of aluminum, silicon, and oxygen). The volcanic activity increases the acidity to high levels and in some stretches of the river, this causes the aluminosilicate particles to reach a diameter of 566nm (instead of 184nm), allowing the sunlight to scatter in the blue lightwave of the spectrum). These particles produce Mie scattering which gives the river its turquoise blue color.
