what makes a National Volcanic Monument?

First, you need Volcano.

Second, you need a visitor center.

Third, once you have a visitor center, you need a parking lot.

Fourth, once you have a parking lot, you need a food supply for the people that use the parking lot.

Once there the people will see denuded landscapes where trees are starting to gain a foothold but even without the trees are full of life. If you come in late spring and early summer, you find beautiful wildflowers. If you are adventurous there are numerous trails around the visitor center that will help you explore the area.
