Equipment If we make the crossing in winter we will be equipped with warm clothing and gloves as temperatures in air are even lower and this must be added the low mobility that is in the basket of the balloon. Flora The highest parts, from 2000 meters are covered with alpine meadows. At lower altitudes find black pine forests and the northern slopes of mountain ranges fir forests. The most interesting plant communities are perhaps growing in the stony, where the loose stones piled high; here among the stones, plants have to adapt to the lack of moisture, the shift of the rocks and low temperatures.
