Description
The Dolomites’ characteristic tower geology — vertical limestone pinnacles carved from the horizontal sedimentary beds of an ancient shallow sea — is fully comprehensible only from the air. Ground photography captures individual towers; aerial photography reveals the complete system — the horizontal sedimentary bedding, the jointing systems that guided erosion into the tower geometry, and the relationship between the peaks and their surrounding glacier-carved valleys. This helicopter photograph was made at 2,800 metres altitude at sunrise, the camera positioned to catch the alpenglow — the warm pink-orange light of first direct sun — on the east-facing Sella towers while the Gardena Valley below remains in the blue-grey shadow of pre-dawn. The colour contrast between the alpenglow-lit vertical limestone and the shadowed valley creates a chiaroscuro that emphasises the Dolomites’ extraordinary vertical relief.
