   Summary Authors:  Andrea Rapposelli,  Stu Witmer

   Seen above are three pictures taken from the  Val Mara visitor
   platform looking into the gorge of the  Gaggiolo River. The rocks
   here, are from the  Middle Triassic (245 -228 million years ago) and
   are primarily from the  Meride Limestone formation. The 65 foot (20
   m) high wall has been laid down over the course of about 60,000 years.
    Each one meter of rock corresponds approximately to 3,000 years.
   These rocks have been studied since the 1930s yielding a  variety of
   species including more than 20 reptiles, 50 fish, over 100
   invertebrates and a variety of plants, mostly conifers. Today  Monte
   San Giorgio is a  UNESCO World Heritage site. Photos taken September
