Did you know that Alaska has almost 175 million acres of land classified as wetlands? That’s almost half of Alaska! That’s also nearly two thirds of the wetlands in all of the United States. Muskegs are a specific kind of bog where only sphagnum moss, black spruce, Sitka spruce, dwarf birch and some other shrubs can grow. One way that we can track these vast wetlands is via satellite. The NASA JPL has images and data available about wetlands in Alaska (and the rest of the globe) available online.
