Marty’s photo of the day #4637: See that circle of ice between the mountains? That’s the headwaters of the Jago River. I shot this photo from a tiny airplane, as Deb and I flew south out of the Arctic National Wildlife Refuge. A few miles to the north, the river had melted, allowing us to canoe 35 miles across the refuge, all the way to the Arctic Ocean.

This adventure is featured in my second book, Endangered Edens: Exploring the Arctic National Wildlife Refuge, Costa Rica, the Everglades, and Puerto Rico.
