The entire circular crater is about 85 km (53 mi) in diameter and 1.3 km (1,300 m; 0.81 mi; 4,300 ft) deep, an area twice the size of Rhode Island, and nearly as deep as the Grand Canyon. However, numerical modeling techniques by Collins et al. indicate that the post-impact diameter was likely to have been around 40 km (25 mi ), rather than the ...
The Zhemchug Canyon is deeper than the Grand Canyon which is 6,093 feet or 1,857 meters deep. [2] It has two main branches, each larger than typical continental margin canyons such as the Monterey Canyon .
As the canyon passes between the peaks of the Namcha Barwa (Namjabarwa) and Gyala Peri mountains, it reaches an average depth of about 5,000 m (16,000 feet) around Namcha Barwa. The canyon's average depth overall is about 2,268 m (7,440 feet), the deepest depth reaches 6,009 m (19,714 feet). This is the greatest canyon depth on land.
Two Grand Canyon-size features on the far side of the moon were likely formed in about 10 minutes after an unknown object slammed into the moon 3.8 billion years ago.
The Grand Canyon [a] is a steep-sided canyon carved by the Colorado River in Arizona, United States.The Grand Canyon is 277 miles (446 km) long, up to 18 miles (29 km) wide and attains a depth of over a mile (6,093 feet or 1,857 meters).
Copper Canyon (Spanish: Barrancas del Cobre) is a group of six distinct canyons in the Sierra Madre Occidental in the southwestern part of the state of Chihuahua in northwestern Mexico that is 65,000 square kilometres (25,000 sq mi) in size.
Here, the river forms one of the deepest canyons in North America, its walls rising as much as 8,200 feet (2,500 m) from river to rim – about half a mile (0.8 km) deeper than the Grand Canyon. [7] The canyons upstream at Cedar Grove are also more than 5,000 feet (1,500 m) deep. [22]
[23] [24] With the adjacent Seven Devils Mountains rising up to 8,000 feet (2,400 m) above the river, Hells Canyon is one of the deepest canyons in North America, almost one-third deeper than the Grand Canyon. [25] Within the canyon it is joined from the left by the Imnaha River, then from the right by its longest tributary, the Salmon River.
