To change things up: some Haiku

Today, breaking from the usual vacation-based poems of the week, I give you a series of Haikus. The trip was beneficial for many things, but my Haiku especially saw a lot of work while I was away. Enjoy:

Man climbs high above

But the earth climbs higher still;

Highest rides the sun.

Each step, hotter fire

Each breath, a chiller embrace—

The sky is thinning.

Fourteen thousand feet,

The world becomes a crystal

Despite summer heat.
