The U.S. Pacific Northwest is in the midst of what's called wildfire season. The dry, warm summer is coming in the region, make conditions right for fires to flare up and the breezes that blow parts of Oregon in particular can cause the flames to spread. But that's only one of nine states in addition to part of Canada that have had areas scorched by recent wildfires. There are dozens of them.

And despite the fact that tens of thousands of firefighters and those supporting are trying to get a handle on all of this, some of the blazes, like Oregon's Eagle Creek Fire were out of control as of last night. Police believe at least one teenager started the blaze by setting off fireworks in the area.

It spread quickly and merged with another fire to destroy at least 22,000 acres. You can think of that like 20,000 football fields. At one point, 153 hikers in the area got trapped between two fires. The National Guard airdropped them supplies to help them get through the night and they were rescued the next day.

But again, that's just one example. These disasters are charring hundreds of thousands of acres from California to Montana and every state between.
