At the far north end of the island of Luzon, in the province of Ilocos Norte, are the Kapurpurawan Rock Formation – “Kapurpurawan” means “white” in the language of the local Ilocano natives.

Limestone is made of skeletal fragments of bazillions of billions of marine organisms. Over billions of years, wind, rain and the waves of the South China Sea have sculpted this alien landscape that has changed little since Spanish explorer Ferdinand Magellan first spotted the Philippines Islands in 1521.

Isabel Sheila Solidum (aka: bell7063) captured this cool image but didn’t share any info about using a polarizer filter, which could account for the otherworldly sky.
