Gigapan.

Photographer David Breashears of GlacierWorks has created a new way of photographing the Himalayan region: By stitching together 400-plus images into one giant, zoomable, interactive image — or a "gigapan" containing more than a billion pixels. He and his team just sent us something even cooler that they're currently working on: a Mount Everest you can explore, containing an estimated 3.8 billion pixels! 

Want to feel very, very small? Be sure to zoom in on the tent city in the lower left.  

NPR has the interactive photo here.
