Despite being one of the most famous and most-visited attractions in the United States, Grand Canyon National Park still holds some surprises. Here are a few facts about the Grand Canyon you probably don’t know.

6. The Grand Canyon creates its own weather

Of all Grand Canyon facts, this one is pretty cool – no pun intended. Sudden changes in elevation have an enormous impact on temperature and precipitation, so the weather you’re experiencing could vary drastically depending on where you are in the Grand Canyon. The coldest, wettest weather station in the region is the Bright Angel Ranger Station on the North Rim, while the hottest (and one of the driest) is just 8 miles away at Phantom Ranch.
