Norway's longest and deepest fjord, the Sognefjord is a geologic and panoramic marvel. The terrain soars upward from the watery depths of the North Atlantic, and many waterfalls punctuatue its edges with spray. The area is accessible only between May 18 and September 15.
The average width of the main branch of the Sognefjorden is about 4.5 kilometres (2.8 mi). Cliffs surrounding the fjord rise almost sheer from the water to heights of 1,000 metres (3,300 ft) and more.
A fjord is formed when a glacier cuts a U-shaped valley on the surrounding bedrock. Most fjords are deeper than the adjacent sea; Sognefjord, Norway, reaches as much as 1,300 m (4,265 ft) below sea level.
