Kingman Reef National Wildlife Refuge

From USFWS National Wildlife Refuge System:

As winter and its chill approach on the mainland, let’s imagine ourselves in south Pacific snorkeling near this pencil urchin at Kingman Reef National Wildlife Refuge (http://bit.ly/2dYB7Cr). Kingman Reef is less than 5 feet in elevation and has no permanent land. Still two small emergent coral rubble spits make it one of the most pristine coral reef atoll ecosystems in the Pacific Ocean.
