Happy National Dog Day! Out on the trail or curled up on the bed, we love our four-legged friends. At Denali National Park in Alaska, sled dogs are important members of the team. Here’s Tephra, a 9-year-old Alaskan husky working her last season before she retires this month. Photo of Tephra posing with fireweed by Miles Leguineche, National Park Service.
Olympic National Park’s rugged shoreline is rich with life. Invertebrates of countless shapes, sizes, colors and textures inhabit the tide pools along Washington’s coast. Pictured here is a starfish with Giant Green Anemones that opens its tentacles like flower petals in the tidal waters. Photo courtesy of Keith Ladzinski.
Take a walk through a winter wonderland at Yellowstone National Park. While it looks a light coating of snow at Tangled Creek, the landscape is covered in hoar frost, which forms when water vapor freezes quickly creating delicate, feather-like crystals.
