The analcime crystals on the Alpe di Siusi plateau found in the pillow lavas are world famous. This layer of the Frommer Lahn, which descends from the Alpe di Siusi plateau towards Siusi allo Sciliar, boasts an enormous, pink and white analcime crystal set in apophyllite. The 66-cm-wide layer, found in a huge hollow in 1966, was too heavy to be carried in a rucksack, which explains why the collector, Alfons Moroder, needed help retrieving it. 

This remarkable 11-cm-wide geode with quartz comes from the Dialer Bohlen area between the Sasso Piatto and Denti di Terra Rossa mountains. This area is famous for its geodes with varieties of quartz often featuring intensive colours. Geodes are formed when hot solutions and gases in hollows contained in pillow lavas crystalize to produce a variety of different minerals. 

This smooth, polished geode from Dialer is intact, filled with brightly coloured concentric agate rings, and is one of the finest specimens of its kind. Geodes occur only in pillow lavas, such as that formed 237-235 million of years ago on the Seiser Alm plateau due to undersea volcanic eruptions. Geodes may often be recovered by hand, while in other cases they require a pickaxe and crowbar.

The calcite crystals in this specimen from Molignon are mounted on glittering Dolomite crystals. Calcite on Dolomite is often formed during the solidification of sediment, particularly through the dolomitisation of limestone sediment. Magnesium-rich solutions replace the calcium in calcium carbonate with magnesium, giving rise to Dolomite rock. This type of rock has a smaller volume than limestone, leading to the formation of irregularly shaped cavities lined with Dolomite and calcite crystals. A famous example is the Molignon cavity with calcite crystals of up to 50 cm in length.

This two-part, 23-cm-high geode with smoky quartz, calcite and geothite was found in the partially rocky mountain pastures at Gardejea - Curasòa and is an impressive example of the minerals of volcanic origin found on the Seiser Alm plateau. This splendid geode dates back to a time between 237 and 235 million years ago, when lava streams full of bubbles coming from the earth's interior collected on sea beds.

An iron tip from a crossbow arrow (14th - 15th century) was discovered by chance on the Alpe di Siusi plateau at Compaccio. This typical medieval attack and defensive weapon is normally found near fortresses.

A hoard of coins or money containing half a kilo of Roman coins was buried and hidden shortly before the year 326 in the Constantine era as an emergency. This was discovered in a dry-stone wall by two builders while digging the foundations of the Eurotel on the Alpe di Siusi plateau. Just nine coins remain out of the original coin hoard; the rest are lost. 

Flint arrowheads, which were attached to the arrow shaft, testify to hunting activity in the high mountains. The stalk of this perfectly preserved arrowhead helped with its insertion into the shaft. The rich hunting grounds on the vast Alpe di Siusi plateau between Compaccio and Sasso Piatto attracted hunters from the early Mesolithic period and continued to attract hunters into the Copper Age, as this find at the Panorama proves.  

Small worked flint pieces (microliths) were excavated at the large dolomite block known as the 'Cionstoan' (Ladin: Sas dla Stria), which is the oldest hunter's shelter yet discovered in South Tyrol. They were parts of the throwing weapons and arrows of Mesolithic hunters. In addition to flint, quartz was also used, though less frequently. This transparent mineral may have been attributed with magical significance.  

Fragments of several 'classic' Laugen jugs (named after the discovery site near Bressanone) were found on the Postal crest at 2400-2500 metres above sea level. They are assumed to be libation vessels that were deliberately smashed during cult acts. The weather-beaten shards of clay from the late Bronze Age are part of a series of discoveries from the Sciliar plateau, which is assumed to have been a fire sacrifice site (1200-1000 B.C.).
