With peaks as high as six kilometers, the icy Tenzing Montes are the highest mountain range on planet Pluto, and were first viewed by the New Horizons Spacecraft in 2015.
The Tenzing Montes /tnz mntiz/ (formerly Norgay Montes) are icy mountains near the Hillary Montes that reach up to 6.2 km (3.9 mi; 20,000 ft) above the surface of the dwarf planet Pluto, bordering the southwest region of Sputnik Planitia in the south of Tombaugh Regio (or the part of Tombaugh Regio south of the equator).
