The National Park Service celebrates its 100th birthday in 2016, and TIME is marking the milestone by publishing Our National Parks at 100. We know you love the parks: a record 307 million people visited them last year, from the depths of the Grand Canyon to the peaks of the Great Smoky Mountains. Now we want to hear from you: vote for your favorite park, and we’ll publish the results in our forthcoming book, which will be gorgeous, informative, and, yes, partially crowd-sourced.
