So, on one hand we have the Jurassic limestones in the south west (Pelisor Valley, Poiana Stanei, Ialomita Valley, Sinaia, Zanoaga Tatarului), and on the other hand we present conglomerates and Cretaceous sandstones in the rest of the massif (Costila, Jepii Mici, Jepii Mari, Caraimanul, Gaura Valley, etc). In the plateau due to erosion sandstones and conglomerates type are witnessing the emergence of a babe that are specific to this mountain range. Bucegii unfolds as altitudes between 900m and 2500m above sea level, culminating in the 2505m peak Omu.
