On June 27th 2009 Dolomites have been declared World Heritage Site The site of the Dolomites comprises a mountain range in the northern Italian Alps, numbering 18 peaks which rise to above 3,000 metres and cover 141,903 ha. It features some of the most beautiful mountain landscapes anywhere, with vertical walls, sheer cliffs and a high density of narrow, deep and long valleys.

A serial property of nine areas that present a diversity of spectacular landscapes of international significance for geomorphology marked by steeples, pinnacles and rock walls, the site also contains glacial landforms and karst systems. It is characterized by dynamic processes with frequent landslides, floods and avalanches. The property also features one of the best examples of the preservation of Mesozoic carbonate platform systems, with fossil records.

The name "Dolomites" is derived from the famous French mineralogist Déodat Gratet de Dolomieu who was the first to describe the rock, dolomite, a type of carbonate rock which is responsible for the characteristic shapes and colour of these mountains; previously they were called the "pallid mountains," and it was only in the early nineteenth century that the name was Frenchified

ENROSADIRA-ALPENGLOW

Alpenglow (from German: Alpenglühen) is an optical phenomenon. When the Sun is just below the horizon, a horizontal red glowing band can sometimes be observed on the opposite horizon. Alpenglow is easiest to observe when mountains are illuminated but can also be observed when the sky is illuminated through backscattering.

Since the Sun is below the horizon, there is no direct path for the light to reach the mountain. Instead, light reflects off airborne snow, water, or ice particles low in the atmosphere. It is this circumstance that separates a normal sunrise or sunset from alpenglow.

Although the term may be loosely applied to any sunrise or sunset light seen on the mountains, true alpenglow is not direct sunlight and is only observed after sunset or before sunrise.

In the absence of mountains, the aerosols in the eastern portion of the sky themselves can still be illuminated in the same way by the remaining red scattered light straddling the border of the Earth’s own shadow (the terminator). This back-scattered light produces a red band opposite the Sun
