4,000 KM LONG · VALLES MARINERIS

4,000 km long — a fifth of the way around Mars, opened by crustal fracture.

≈ 85 KM Ø

Only 108 million years old. Its rays still streak 1,500 km across the Moon.

WHERE LAVA MEETS THE SEA

Basalt shattered by the sea into black sand. Green sea turtles bask on the shore.

26 ACTIVE GLACIERS

An active volcano and the most glaciated peak in the lower 48. Source of six rivers.

8 TONS PER SQUARE INCH · CHALLENGER DEEP

Deeper than Everest is tall. Sunlight has never reached the floor.

The only fourteener in Rocky Mountain National Park. The Keyhole is a Class 3 scramble.

↑ 13,775 FT · OWEN-SPALDING

First documented ascent 1898. The 1872 claim is still debated.

↑ 18,000 FT BASE-TO-PEAK
