A tour of Grand Canyon National Park prepared for its centennial last year. Original caption:

Here is my homage to the centennial celebration of the Grand Canyon National Park. Obviously the canyon itself is considerably older than that. I've had some many good times at the canyon since I was young and have many more trips planned. As the storms sweep across with the powerful downpours I know that little carving is occurring in the canyon on this day. The amount of water, wind and time to to erode what we see today is beyond my ability to conceive.

This article on John Wesley Powell, who famously explored the Grand Canyon area and after whom Lake Powell is named, explores his so-called anthropological studies of the Native populations and his belief that those populations needed to be "Civilized". An illustration of the choices we are making when we tell certain parts of a story to glorify an individual, while leaving other parts to a legacy that isn't discussed.

Arizona and California road trip. Original caption:

Home. For some home is the scorching desert. For others, it's the lush California Valley. For some, home is running away from it. Home isn't one place, it's a feeling.

The rim above the clouds

These photos capture clouds filling almost the entire Grand Canyon due to a temperature inversion.

Cold, humid, and foggy air is denser than warm air, so if the air is stable enough it is possible for a weather pattern to form where a dense, foggy layer of air sits in the canyon and is held in place by the warmer air above it.

These inversions are not uncommon, typically occurring in the Canyon once every year or every few years. This one is particularly impressive since the boundary layer is so close to the actual canyon rim.
