Name as many of the official units of the US National Park System as you can. Some units compromise large land areas (large parks, trails, rivers), so the location on the map is somewhat approximate. Completing states is only done when you complete all the units entirely within that one state, so you can complete all 54 states/territories before getting all the answers (as there are units which cover multiple states). Names need to be known reasonably well, however last names suffice for places dedicated to just one person. Battlefields include all battlefield/military parks/sites. Some places, such as monuments, are not under the NPS, therefore are not on this quiz. Note – there is one location in the Pacific you may have to scroll westward to view.
