The Rivoli-Avigliana Morainic Amphitheatre also known as Rivoli-Avigliana end moraine system, located at the outlet of the Susa Valley (Dora Riparia basin) in Western Alps, is the westernmost of the end moraine systems that reach the alluvial Po Plain. Unlike other end moraine systems located on the southern side of the Alps (e.g. Ivrea, Garda, Tagliamento), the Rivoli-Avigliana amphitheatre shows an unusual 'bullet shape' instead of the 'classic' concentric arcuate pattern.
The morainic amphitheatre extends at the mouth of the Susa Valley over an area of about 180 km2. It is bordered by the Sangone and Casternone-Ceronda streams to the south and north, respectively. A complete reorganisation of the hydrographic network occurred since the first maximum glacial expansion documented in the area (Early-Middle Pleistocene), with the Sangone stream, once a right tributary of the Dora Riparia, forced to abandon the N-S trending depression beneath the present Lago Grande and Lago Piccolo and then flow south of the the NNW-SSE-trending inselberg of the Mt. Moncuni (641 m a.s.l.). Similarly, the Casternone stream has undergone a northward migration with respect to its original course as evidenced by its arcuate shape. During the Lateglacial phase, the Dora Riparia glacial front halted repeatedly, as evidenced by frontal moraines south of Avigliana and between Caselette and Rosta, causing the formation of some dammed lakes (i.e. Lago Piccolo and Lago Grande). The last phase of alluvial sedimentation in the lower Susa Valley (Holocene) is characterised by a thin layer (5–15 m) of coarse-grained alluvial deposits and sporadic peat bogs (e.g. Villar Dora, Novaretto, Avigliana and Trana). Fossil wood remains collected near Villar Dora have been dated by Charrier and Peretti (1975) at 11,805–11,253 cal. years BP, whereas Charrier and Peretti (1975) dated peat layers sampled in some quarries near Novaretto at 8,980–8,385 cal. years BP.
The amphiteatre is characterised by a large lithologic variety derived from the bedrock of the Dora Riparia catchment, made up of continental and oceanic nappe systems belonging to the Pennidic domain.
Very large serpentinite and metabasite erratic boulders are observable in some places. The 'Masso Gastaldi', located in the centre of Pianezza (7°33′01″ E, 45°05′56″ N), is the largest erratic in the amphitheatre (38 m long, 25 m wide and 14 m high), whereas the 'Pera Majana' is a serpentinite boulder, 32 m long, 23 m wide and 6 m high, abandoned in the centre of a large outwash channel close to Villarbasse (7°28′43″ E, 45°02′35″ N).
