A wildfire that destroyed a historic Grand Canyon lodge is continuing to spread out of control after it had been allowed to burn for days.

Some effects of Arizona's Dragon Bravo Fire are clear, but what's happened to wildlife may not be known until the flames die down.

The Dragon Bravo Fire has left a path of destruction in the Grand Canyon's North Rim, burning down the historic Grand Canyon Lodge. The National Park Service on July 19 released photos of the park, showing burned-down structures, charred mountainsides and a smoke-filled canyon.

A combination of high winds, dry air and above average temperatures caused a wildfire in the Grand Canyon to rapidly expand and cause major damage.

The American Red Cross is deploying crews on the ground in northern Arizona to help families impacted by the Dragon Bravo and White Sage wildfires.

The building was surrounded by vegetation on fire when a team of "helitack" firefighters arrived to protect the area on Tuesday. Grand Canyon National Park officials said the crews knew if the pump house fell, the consequences could cripple park operations for months.

U.S. land managers have long known that they have a problem on their hands with overgrown forests and persistent drought.

The fast-moving fire destroyed a historic lodge and dozens of other structures in the Grand Canyon National Park.
