Hint 4: A National Park Visitors Center is just off the left side of this map
Hint 3: Part of a National Park in this map. Just a reminder, you need to name a feature in the map, so just saying the name of a national park is not good enough
Hint 2: This is in Utah
Hint 1: This area drains into the Colorado River
This is one of my favorite looking ones recently, Good Luck!
