Starting with a large, block number 2016 to signify the year of the annivesary, this logo takes a recognizable shape that holds the National Park Serivice's primary logo - a downward pointing arrowhead - and swaps that for the number zero in a slightly lighter green. Below the number sits a word mark with the name of the organization and the word "Centennial" below in the same green as the arrowhead.
