It's about as tall as Maxwell Montes
(Ishtar Terra, Venus)
Maxwell Montes rises to a total height of 12,000 yards. 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-tenth times as tall as The Challenger Deep (Marianas Trench)
In other words, 12,000 yards is 1.0065 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 0.993540 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 11,923 yards 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 one-and-one-fifth times as tall as a Mauna Loa
In other words, 12,000 yards is 1.1970 times the height of a Mauna Loa, and the height of a Mauna Loa is 0.83540 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 10,060 yards 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 one-and-one-fourth times as tall as Mount Everest
In other words, 12,000 yards is 1.240 times the height of Mount Everest, and the height of Mount Everest is 0.8060 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 is 9,680 yards above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak â€” raising it by 0.00437 yards and shifting it to the northeast by 0.00492 yards each year.
It's about one-and-three-fifths times as tall as Aconcagua
In other words, 12,000 yards is 1.57610 times the height of Aconcagua, and the height of Aconcagua is 0.634480 times that amount.(a.k.a. Cerro Aconcagua) (Mendoza, Argentina)
Aconcagua measures 7,613.60 yards 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 5,686.80 yards high ridge.
It's about one-and-three-fifths times as long as The Las Vegas Strip
In other words, the length of The Las Vegas Strip is 0.630 times 12,000 yards.(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 7,400 yards 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 26,000,000 yards of neon light tubing.
It's about one-and-three-fourths times as tall as Denali
In other words, 12,000 yards is 1.7720 times the height of Denali, and the height of Denali is 0.56430 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 6,773 yards 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.
