It's about as tall as Mount Everest.
In other words, the height of Mount Everest is 1 times 29,000 feet.(a.k.a. Mount Chomolungma, 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 is 29,000 feet above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.0131 feet and shifting it to the northeast by 0.0148 feet each year.
It's about as tall as a Mauna Loa.
In other words, the height of a Mauna Loa is 1.037 times 29,000 feet.(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 30,180 feet 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 four-fifths as tall as The Challenger Deep (Marianas Trench).
In other words, 29,000 feet is 0.810790 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 1.23340 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 35,768 feet below sea level. There has been only one manned expedition to the bottom of Challenger Deep — a 1960 voyage that took 4 hours and 48 minutes to reach the bottom.
It's about four-fifths as tall as Maxwell Montes.
In other words, the height of Maxwell Montes is 1.30 times 29,000 feet.(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 36,000 feet. 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 one-and-one-fourth times as tall as Aconcagua.
In other words, 29,000 feet is 1.26970 times the height of Aconcagua, and the height of Aconcagua is 0.787590 times that amount.(a.k.a. Cerro Aconcagua) (Mendoza, Argentina)
Aconcagua measures 22,841 feet 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 17,060 feet high ridge.
It's about one-and-three-tenths times as long as The Las Vegas Strip.
In other words, the length of The Las Vegas Strip is 0.770 times 29,000 feet.(Las Vegas Boulevard S and W from Russel Rd to Sahara Ave)(Paradise, Nevada through Winchester, Nevada).
Although technically located beyond the city limits of Las Vegas (along with the well-known "Welcome to Fabulous Las Vegas" sign), the stretch of road known as the "Las Vegas Strip" runs 22,000 feet along Las Vegas Boulevard South and West from Russel Road at the south end to Sahara Avenue at the north end. The casinos and hotels on the Strip display an estimated total of 79,000,000 feet of neon light tubing.
It's about one-and-two-fifths times as tall as Denali.
In other words, 29,000 feet is 1.4270 times the height of Denali, and the height of Denali is 0.70080 times that amount.(a.k.a. Mount McKinley, a.k.a. Doleika, a.k.a. Traleika, a.k.a. "The Great One") (Denali National Park and Preserve, Alaska) (South peak)
The highest mountain peak in North America, Denali's South Peak measures 20,320 feet above sea level at its peak. The impetus for the name Mount McKinley was US president William McKinley of Ohio, and disputes over the which of the mountain's names should be officially recognized regularly occur between Ohio Congressmen and Alaska politicians.
