The higher region of the Alps were long left to the exclusiveattention of the men of the adjoining valleys, even when Alpine travellers began to visit these valleys. It is reckoned that about 20 glacier passes were certainly known before 1600, about 25 more before 1700, and yet another 20 before...

 is not fixed. The occurrence of favorable meteorological conditions during several successive seasons can increase the extent of the snowfields and lower the limit of seemingly permanent snow, while the opposite may cause the limit to rise higher on the flanks of the mountains. In some parts of the Alps the limit is about 2,400 m elevation, while in others it cannot be placed much below 2,900 m. As very little snow remains on rocks angled more than 60°, this is soon removed by the wind, some steep masses of rock remain bare even near the summits of the highest peaks, but as almost every spot offering the least hold for vegetation is covered with snow, few flowering plants are seen above 3,350 m..

The climate of the glacial region has often been compared to that of the polar region

Earth's polar regions are the areas of the globe surrounding the poles also known as frigid zones. The North Pole and South Pole being the centers, these regions are dominated by the polar ice caps, resting respectively on the Arctic Ocean and the continent of Antarctica...

s, but they are very different. Here, intense solar radiation by day, which raises the surface when dry to a temperature approaching 27°C, alternates with severe frost by night. There, the Sun, which never sets is only able to send feeble rays that maintain a low temperature, rarely rising more than a few degrees above the freezing point. Hence the upper region of the Alps sustains a far more varied and brilliant vegetation.
