As you probably know, the majority of the Grand Canyon is a protected National Park that encompasses nearly 1,217,262 acres (492,608 ha) of land in Arizona.  The gorge, carved over centuries by the Colorado River, is the main attraction.  Flights over the national park are restricted from flying under 18,000 feet except for a small, dedicated space managed by the Hualapai Indian Tribe which has been made accessible for air-tourism in and out of the canyon.  The helicopter companies pay a hefty amount for the privilege of being able to land by the Colorado River.  All the helicopter operators are environmentally conscious of the fragility of the desert landscape and make a valid effort to be responsible stewards of the land.

 

We are very fortunate that this pristine spot of grandeur on earth has been made available for our enlightenment and enjoyment.
