This is a photo of the Santa Elena Canyon in Big Bend. The Rio Grande River run through and created the canyon. It looks very much like a “V” in this view. But from inside the canyon, the walls look almost straight up. Mostly, this is because you can’t see the tops of the walls from the bottom. Also, I think this view makes it look a little more V-shaped than it really is in the inner part of the canyon.
A reminder that distance (and time) gives a different perspective. It may be more accurate, but may be less so.
