It's about as tall as Olympus Mons
(a.k.a. Mount Olympus) (Mars)
The tallest mountain in the solar system, Olympus Mons rises to approximately 16,000 smoots. The mountain has been known to astronomers since the nineteenth century because it is tall enough to rise above Mars' frequent dust storms.
It's about two-and-a-half times as deep as The Challenger Deep (Marianas Trench)
In other words, 16,000 smoots is 2.49760 times the depth of The Challenger Deep (Marianas Trench), and the depth of The Challenger Deep (Marianas Trench) is 0.400380 times that amount.(near Marianas Islands, a.k.a. Ladrones Islands, northwestern Pacific Ocean) (depth below sea level)
The Challenger Deep, at the southern end of the Marianas Trench, reaches a depth of 6,406.20 smoots below sea level. The first manned expedition to the bottom of Challenger Deep took 4 hours and 48 minutes in 1960. This was the only manned descent to the floor of the Trench until 2012, when director James Cameron made the trip; several other descents have been made since then.
It's about two-and-a-half times as tall as Maxwell Montes
In other words, the height of Maxwell Montes is 0.40 times 16,000 smoots.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 6,500 smoots. Since Venus does not seem to have the kind of tectonic activity which gives rise to mountains on Earth, the origin of the Venusian mountain remains the subject of some dispute.
It's about three times as tall as a Mauna Loa
In other words, 16,000 smoots is 2.970 times the height of a Mauna Loa, and the height of a Mauna Loa is 0.33670 times that amount.(Hawaii) (Hawaiian island volcano) (total height from seafloor)
Mauna Loa, one of the five volcanoes which forms the island of Hawaii and the tallest mountain in total height in the world, rises to 5,406 smoots above the seafloor. The peak of Loa is home to the approximately 6,000 sq. m (0.6 ha) Lake Waiau, one of the highest altitude lakes in the United States outside of Colorado.
It's about three times as tall as Mount Everest
In other words, 16,000 smoots is 3.0771 times the height of Mount Everest, and the height of Mount Everest is 0.3249810 times that amount.(a.k.a. Mount Chomolungma, a.k.a. Sagarmatha, a.k.a. Mount Qomolangma, a.k.a. सगरमाथा, a.k.a. Chajamlungma, a.k.a. ཇོ་མོ་གླང་མ, a.k.a. 珠穆朗玛峰, a.k.a. Zhūmùlǎngmǎ Fēng) (Sagarmatha Zone, Nepal and Tibet, China) (to summit, excluding snow depth)
Mount Everest rises 5,199.710 smoots above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak â€” raising it by 0.00235045 smoots and shifting it to the northeast by 0.00264426 smoots each year.
It's about three-tenths as long as The Panama Canal
In other words, 16,000 smoots is 0.310 times the length of The Panama Canal, and the length of The Panama Canal is 3.20 times that amount.(Canal de Panamá) (Panama)
Connecting the Atlantic and Pacific Oceans across the Isthmus of Panama, the Canal measures 52,000 smoots in length. Ships passing through the Canal are raised (and then lowered) 15 smoots above sea level through the lock-and-dam system.
It's about four times as tall as Aconcagua
In other words, 16,000 smoots is 3.91110 times the height of Aconcagua, and the height of Aconcagua is 0.255680 times that amount.(a.k.a. Cerro Aconcagua) (Mendoza, Argentina)
Aconcagua measures 4,090.90 smoots height at its peak. Although there is no definitive evidence that members of the indigenous Inca civilization ever reached the peak the mountain, numerous archeological sites have been found on the slopes of the mountain, including a naturally-embalmed Incan mummy was discovered on a 3,055.60 smoots high ridge.
