A sweet wintry photoset from the Sierras this December. Little snow cover on the ground, hiking in to a fire tower to spend two toasty nights. Waking up to creaking ice on the wooden roof and delicate hoarfrost crystals on the catwalk. Jeffrey pines encrusted in frost, mysterious valley fog rising up to cover the view of the fields and valleys below. A rushing stream flows over and under the Pacific Crest Trail.
