Exploring the Deepest Point on Earth

Challenger Deep is deep. Very Deep. Located in the Mariana Trench, Challenger Deep is the deepest known point in the Earth's seabed. But just How Deep is Challenger Deep?

John Nelson has the answer in this beautiful Esri story map which helps to explain the staggering depths of Challenger Deep. As you progress through this story map you will learn about the natural forces which created this huge depression deep beneath the Pacific Ocean. You will also learn about the kind of dark inhospitable conditions which exist at so many fathoms beneath the sea.

As is customary John Nelson's story map contains some beautiful cartography, liberally sprinkled with Nelson's own patented Firefly mapping technique and some interesting comparative illustrations.

To help convey the staggering depth of Challenger Deep Nelson uses a number of non-standardized units of measurement. This involves showing how many Everests, Manhattans or Grand Canyons deep the depression falls beneath the surface of the sea. To help illustrate these non-standardized units of measurement Nelson has stacked a number of Mount Everests one on top of the other and relocated the Burj Khalifa to the bottom of the Grand Canyon. All for a sense of scale - of course.
