Starting with 35 sites, National Parks now oversees over 400 sites in the U.S. and its territories. In honor of today, Howard printed a cut of an animal that has become an iconic symbol of both National Parks and our friends at California State Parks. #OnThisDay #nationalpark #sacramento | Sacramento History Museum | Facebook

It's snowing up at Mount Rose! Thanks to the Nevada Seismological Lab for capturing this beautiful time lapse illustrating how quickly the weather can change here. As you can see, a mix of precipitation is starting to enter into the region. This will continue throughout the rest of the day. If you are traveling on the passes today, make sure to drive with caution as roads may be slick. #Juneuary @NVSeismoLab | US National Weather Service Reno Nevada
