I forget. Does the southern hemisphere celebrate Christmas in July? Mmm.
Christmas Island is a territory of Australia, about 1600 miles northwest of Perth. (Singapore is actually closer on the northern side, though.) Wikipedia tells that it was named by Captain William Mynors of the British East India Company when he sailed past on Christmas Day in 1643.
The island has a notable lagoon visible from the photograph, and is about 52 square miles in area. (That is a little smaller than St. Petersburg, Florida.) The Christmas Island website explains the island is the summit of a submarine mountain, composing the island of almost all volcanic rock. As a mountain summit, the island has a coastline that is almost continuous sea cliff, up to 65 feet in height. Better pack an umbrella, it receives 76 inches of rain a year.
Over 60 percent of the island's area is a national park. The rainforests and and fringing reef are protected by the Australian government. There are 16 types of ferns found only on Christmas Island.
Christmas Island has rich phosphate deposits from eons of dead marine animals when it was underwater. The mining operation was closed in 1987 after the deposits were depleted. It has since been reopened with many of the former workers as part-owners. Other than that, the primary industry is tourism. You can check out the available accommodations at the Christmas Island Tourism Association.
