Geomorphologically, the mountain is a mesa-like outlier, that is to say, the remains of a plateau that has been otherwise eroded to leave only a single pillar of rock - weaker or fractured rocks (the so-called Jasneuf fault) between the current summit and the Vercors high plateau were eroded over time by over 400 metres, leaving the peak standing on its own. This has resulted in several unique features of Mont Aiguille, including the cliffs, which are almost identical to those on the eastern edge of the Vercors Plateau such as those on the edge of the Grand Veymont, which is the highest point of the range. Another feature resulting from this is the presence of meadows on the summit plateau, which are similar to those to the west on the rest of the Vercors plateau.
