E 'in this context that places the Lago di Pilato. Located in the Parco dei Monti Sibillini is the only natural lake in the Marche region and certainly one of the last glacial lakes left in' Apennines. At 1949 m above sea level, is located in a basin, a circle with glacial moraine deposits a clear sign of the glaciers were present during the Quaternary. Surrounded by the highest peaks of the Sibillini Mountains (Mount Carrier - 2476 m, tip Lawn Clean - 2373 m, Cima del Lago - 2422 m, Cima of the Redeemer - 2448 m, Devil's Peak - 2410 m) in the season of its greatest reservoir is around 500 m deep, 15-20 m and wide in its central part , 125-150 m.
Lago di Pilato - July 2006 Its origins, as we have already mentioned, are to be dated to about a million years ago when, during the last glaciations (Riss and Wurm), the slow but relentless action of the ice has made a significant contribution to shaping land, creating the typical U-profiles and moraines. Last traces of the glacier are snowfields semiperenni surrounding the pond. Given the presence in the surrounding area of \u200b\u200bkarst basins and was considered that its origin is also determined from the karst, as well as glacial. A time of egg-shaped, today takes the form feature "to glasses." In winter, the lake does not exist in practice, being replaced by a blanket of snow, uniform thickness of several meters.

| | With the melting of the snows, the lake begins to appear that at the time of the maximum reservoir, has a unique body ; language moraine is, in fact, partially flooded and the lake takes on the precise form of a pair of glasses together by thin bridge Central. With the decrease of the contribution of snow, the lake level on down, finds itself increasingly the moraine, to divide the body of water into two parts. This division is most evident in recent decades because of the continuing number of landslide debris from the surrounding mountains. Moreover, in the absence of tributary water level undergoes strong oscillations
summer. The envoy, however, is underground. The only clue we have of this effluent in the spring. During this time, but sometimes in early summer, you can see near the lake, a little further downstream, the Source of the Lake, the only source of this valley (in addition to Source Matta but being "crazy" not is always present). Lake is considered by many to be also the true source of the river Aso
. This river shows its course on the surface only by Mouth of
Montemonaco , so it is always used to indicate the source of the river like this.
in the area surrounding the severe weather does not allow the growth of tree species. The vegetation is thus constituted an altitude grasslands dominated by grasses such as Sesleria
Apennines, the fescue and fescue dimorphic purple. These prairies are characterized also for the presence of a large number of species rare and endemic plant species, exclusive of the main Apennines, as edelweiss Apennines, the ginepì
Apennines Apennine yellow poppies and several species of saxifrage.

Regarding the fauna, however, are typical of high mountain environments. Among the birds include the rock partridge, the peregrine falcon
, the snow finch, the Sardone, the alpine chough and the coral. It 'also present the Orsini Viper, a snake that almost harmless in Italy is only the highest peaks of the central high. The lake has a remarkable richness of pelagic zooplankton. In 1953-54, during a search campaign hydrobiological
, organized by the Institute of Botany at the University of Camerino, was discovered the presence in the lake, a new species of crustacean. It was called the
Chirocefalo Marchesoni (
Chirocephallelus
Marchesonii
), named after the discoverer. This small crustacean (1 cm in length) lives here and nowhere else in the world. His movements are very slow, so it's easy to pass a hand under, while swimming, and take it in the palm. But this would be a cruel mistake: the
Chirocefalo is accustomed to the temperature of his water, just above zero, so it is enough to stay for a few minutes for the water held in the palm to get up a few degrees, and the animal enters into crisis and die.  |

In 1990 it ran a very serious danger of extinction, when, after two summers particularly drought, the lake dried up. While the level down inexorably, in the frenzy of wanting save
Chirocefalo , the experts made proposals, the most viable of which seemed to carry water (in fact, ice cubes) with a shuttle of helicopters and airplanes.
Providentially, the project is implemented, because the difference in temperature, and the different rate of acidity that would have had the new water would be fatal to the shrimp. The lake, therefore, in the summer of 1990, dried up, and saw many
at the end of this Chirocefalo .  |

particularly generous in terms of rainfall
snow, so much so that
Castelluccio di Norcia, at the foot of the Carrier, was a measured thickness of 14 meters! With the reform of the lake in spring, but here is the
Chirocefalo leap out again, more lively and perky as ever. What had happened? Simple: the
Chirocefalo was, yes, dead, but before his death had laid her eggs, which, unlike its owner
have a rather extraordinary
resistance, so it can withstand up to two years drought, hidden under the stones of the fund. With the arrival of the water, the eggs were hatched and the shrimp had begun to give the charm of the lake.
Since 1990 there was also another occasion when the lake of Pilato risk of disappearing. To really dangerous in these two periods was primarily the can
