See these elk at Tule Elk San Luis National Wildlife Refuge. Once estimated to have a population of less than 30 individuals, these unique California Tule elk now number more than 4,000. See them – and other terrific wildlife – just two hours outside of San Francisco. Photo by Lee Eastman, U.S. Fish and Wildlife Service. Posted on Tumblr by the US Department of the Interior, 9/23/16.
Fall at Denali National Park in Alaska means gorgeous autumn colors and hungry brown bears. To get ready their long winter sleep, bears spend the summer and fall packing on the pounds – gorging themselves on salmon, berries and grass. Sleeping snugly in their dens, breathing only once a minute and dropping their heart rate to 8-10 beats a minute, bears will live on their fat stores during the dark, cold winter. Photo by Jacob W.
