The Sabche Cirque in question looks like a fascinating, and difficult place to explore. Check out narrow the exit drainage is! https://www.researchgate.net/figure/Deep-and-narrow-gorge-of-the-Seti-River-at-the-outlet-of-Sabche-Cirque-Avalanches-and_fig2_354413412 https://www.researchgate.net/figure/Deep-and-narrow-gorge-of... This Nasa blog post has a lot of good pictures of the immediate area that helps with understanding the shapes of the mountains there. I initially didn't realize just how choked down the drainage got.
