As of today, peak season now, through ~July 31. Earth Exhibit tracks the live conditions and flags it the moment it is on.
In several Chapada Diamantina caves a narrow opening or skylight aligns with the sun for a limited season each year, producing a short-lived beam that illuminates the clear subterranean pools and makes the water glow intense blue.
The effect is driven by geometry (sun angle and cave opening), clear skies, and the extreme clarity of the karst waters.
