Over time, the geology of the massif made it possible to dig a basin and create a rocky edge. It is this “glacial lock” which erases Port Bielh Lake from the landscape when you are below.
Apart from a few pines, you will not find much vegetation there. The site is essentially mineral but still offers small lawns suitable for bivouacs.
