Yellowstone National Park

Yellowstone is famously known for being a supervolcano, with the caldera as its crater. The caldera boundary is a brighter magenta than the NPS's original symbology—a stark contrast to the yellow hues on the rest of the map.

Mountains, geysers, and waterfalls are now represented by symbols resembling these features. Because these physical features are all aesthetic spots that attract tourists, it is imperative that this map calls a viewer’s attention to them.

This feature divides watersheds that flow into the Pacific Ocean and the Atlantic Ocean. This new map changed the stroke and label colors from orange-yellow (on the NPS map) to a dark blue because the Continental Divide is inherently a hydrologic feature.

The NPS brochure map only used sans serif fonts, which was edited to reflect effective cartographic principles—natural features are labelled with serif fonts, and hydrologic labels are italicized.
