It's about eight times as long as a Football field.
In other words, 857 meters is 7.810220 times the length of a Football field, and the length of a Football field is 0.1280370 times that amount.(American) (total distance; per NFL regulation)
According to NFL specifications, an American football field should measure 109.7280 meters from end to end. Because each team's goalpost is located at the far end of the scoring area (end zone), a ball on a scoring play may need to travel as many as 9.1440 meters farther when kicked into the scoring area than when run (rushed) or passed into it.
It's about one-tenth as tall as Aconcagua.
In other words, 857 meters is 0.12310 times the height of Aconcagua, and the height of Aconcagua is 8.12350 times that amount.(a.k.a. Cerro Aconcagua) (Mendoza, Argentina)
Aconcagua measures 6,961.9 m 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 5,200 m high ridge.
It's about eight times as long as a Football (Soccer) Pitch.
In other words, 857 meters is 8.160 times the length of a Football (Soccer) Pitch, and the length of a Football (Soccer) Pitch is 0.1230 times that amount.(a.k.a. Football Field, a.k.a. Soccer Field) (field length, a.k.a. touchline distance)

It's about one-tenth as tall as Mount Everest.
In other words, 857 meters is 0.0968 times the height of Mount Everest, and the height of Mount Everest is 10.30 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 8,850 m above sea level at its summit. The plate tectonics of the Indian subcontinent continuously alter the mountain's peak — raising it by 0.004 meters and shifting it to the northeast by 0.0045 meters each year.
It's about one-tenth as tall as a Mauna Loa.
In other words, 857 meters is 0.09348 times the height of a Mauna Loa, and the height of a Mauna Loa is 10.70 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 9,168 m above the seafloor.
