Think Pink

Today's doodle looks a bit like an extraterrestrial creature, but I assure you, it's actually a map.

My Crayola sketch doesn't do this lake justice. Here's a real picture of it.

Lake Hillier isn't the only pink lake in the world. It's color alone doesn't make it special. What's different about this lake is that scientists have determined it isn't algae that give Lake Hillier it's pink hue. That's what causes the color in the other lakes. Lake Hillier maintains its pinkness even when water samples are removed. It also doesn't change with the seasons the way the algal lakes do. The reason for its pinkness remains a mystery, and the island is strictly for research purposes. Tourists are only able to admire the pink beauty from above via helicopter rides.
