Translation of "Gorge" in Japanese

Okay look, this our way out of this gorge.

峡谷(きょうこく)の出口だぞ

So you wanna rappel down the side of this into the gorge?

ロープで峡谷(きょうこく)に 下りたいんだな？

[Bear] Rappelling into that gorge has taken us off the cold chain route

ロープで下りて ルートから外れた

So you want me to try and cross this gorge and then stay on the high ground?

この谷間をわたって 高い所を進むんだな？
