Experts Speak
One geologist has gone on to state that the Denman Glacier is classified as the deepest canyon on land, which is commonly confused with trenches in the ocean. Until the developments made from the BedMachine Project, all previous efforts to map this valley failed.
Entrenched
Scientists have gone on to say that the trough is so entrenched that you’re able to get side-echoes from the walls of this valley. It’s for this reason that it’s almost impossible to detect the reflection from the actual bed. However, these researchers have been able to catch a glimpse of the glory this canyon has.
