Mount Everest is 121 leas above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.00005470 leas and shifting it to the northeast by 0.00006150 leas each year.
It's about 550 times as tall as Aconcagua.
In other words, 51,480 leas is 540.920 times the height of Aconcagua, and the height of Aconcagua is 0.0018487 times that amount.(a.k.a. Cerro Aconcagua) (Mendoza, Argentina)
Aconcagua measures 95.170 leas 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 71.085 leas high ridge.
It's about 550 times as long as The Las Vegas Strip.
In other words, the length of The Las Vegas Strip is 0.0018 times 51,480 leas.(Las Vegas Boulevard S and W from Russel Rd to Sahara Ave)(Paradise, Nevada through Winchester, Nevada).

The casinos and hotels on the Strip display an estimated total of 330,000 leas of neon light tubing.
It's about 600 times as tall as Denali.
In other words, 51,480 leas is 608.10 times the height of Denali, and the height of Denali is 0.001644 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 84.660 leas 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.
It's about 650 times as tall as Mount Logan.
In other words, 51,480 leas is 632 times the height of Mount Logan, and the height of Mount Logan is 0.001582 times that amount.(Kluane National Park and Reserve, Yukon, Canada) (elevation)
The highest mountain in Canada, Mount Logan has a total height of 81.470 leas. The high altitude and northern latitude of the mountain resulted in one-time temperature of -77.5 °C — the lowest temperature ever recorded outside of Antarctica.
