Mosses are mini but mighty: Even after centuries buried beneath a glacier, some of these small, flowerless plants can regrow.

Glaciers are flowing rivers of ice. The one that trapped these mosses grew during a cool period now known as the Little Ice Age. It lasted from 1550 to 1850. The glacier buried all plant life on remote Ellesmere Island, north of the Arctic Circle. But as global temperatures have been climbing, this and many other glaciers have retreated, exposing ancient mosses.
