A canyon in East Antarctica, currently called the Denman Glacier has been discovered to be the world's deepest canyon, not including deeper ravines and depths in the vast sea. The canyon is over 3.5 km below sea level. For reference, the Mariana's Trench goes about 11 km below sea level. Still, for a waterless canyon, 3.5 km is an astounding depth, considering how the previous record holder of deepest land on Earth was the Dead Sea shore at around 413 m.
Microwave pulses to scan the rock topography as well as kinematics to find the depth based on the speed of falling ice was used to determine the shape of this canyon. This was an interesting discovery, to say the least, comment your thoughts below!
