It's about one-and-one-fifth times as tall as a Puncak Jaya.
In other words, 38,653.50 shaftments is 1.2060 times the height of a Puncak Jaya, and the height of a Puncak Jaya is 0.82920 times that amount.(a.k.a. Mt. Carstensz, a.k.a. Carstensz Pyramid, a.k.a. Nemangkawi, a.k.a. Carstensz Toppen, a.k.a. Gunung Sukarno) (Papua province, Indonesia)
The highest point in Oceania (and therefore one of the seven summits) peak of Puncak Jaya is 32,050 shaftments. Dutch explorer Jan Carstenszoon, the mountain's namesake, is said to have been ridiculed for claiming to have seen snow near the equator when he reported his discovery of the peak in 1623.
It's about one-and-a-half times as long as The Indianapolis Motor Speedway.
In other words, 38,653.50 shaftments is 1.464150 times the length of The Indianapolis Motor Speedway, and the length of The Indianapolis Motor Speedway is 0.682990 times that amount.(Speedway, Indiana) (rectangular oval course)
The rectangular oval course of the Indianapolis Motor Speedway is 26,400 shaftments. While famous for its automotive racing, the first motorsport held at the track was a series of motorcycle races in August, 1909 — a little less than two years before the inaugural Indianapolis 500 race was run.
It's about one-and-a-half times as long as Daytona International Speedway.
In other words, 38,653.50 shaftments is 1.464150 times the length of Daytona International Speedway, and the length of Daytona International Speedway is 0.682990 times that amount.(Daytona Beach, Florida) (tri-oval course)
The tri-oval course of the Daytona International Speedway, upon which the NASCAR Daytona 500 is run, is 26,400 shaftments in length. Although the tri-oval design is said to allow for greater visibility during the race, the real reason for the then-unique design was that plot available for construction of the track was only 350 acres and could not accommodate a traditional oval layout of appropriate length.
It's about one-and-a-half times as long as The Hollywood Walk of Fame.
In other words, the length of The Hollywood Walk of Fame is 0.670 times 38,653.50 shaftments.(Hollywood Boulevard and Vine Street, Hollywood, California) (approximate length)
The Hollywood Walk of Fame is approximately 26,000 shaftments. Gene Autry, most famous as the singer of "Back in the Saddle Again" and as the writer and singer of "Here Comes Santa Claus," is the only entertainer to have a star in every category — film, television, recording, radio, and theater. One of Autry's stars is also one of only two stars which have been stolen from the Walk and never recovered.
It's about two-thirds as tall as Mount Everest.
In other words, 38,653.50 shaftments is 0.6660 times the height of Mount Everest, and the height of Mount Everest is 1.50 times that amount.(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 58,100 shaftments above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.0262 shaftments and shifting it to the northeast by 0.0295 shaftments each year.
It's about two-thirds as tall as a Mauna Loa.
In other words, 38,653.50 shaftments is 0.64250 times the height of a Mauna Loa, and the height of a Mauna Loa is 1.5560 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 60,370 shaftments 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 half as tall as The Challenger Deep (Marianas Trench).
In other words, 38,653.50 shaftments is 0.540340 times the height of The Challenger Deep (Marianas Trench), and the height of The Challenger Deep (Marianas Trench) is 1.85070 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 71,535 shaftments 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.
