Stars in the flowing water
by Katja Laute, Trondheim, Norway
At a certain spot in the upper glacier-connected Erdalen valley, a small glacial creek is flowing over the exposed bedrock and has perfectly polished its surface. The clear water impressively highlights the gneissic banding including alternating darker and lighter coloured bands of the predominant orthogneiss. The characteristic banding developed under high temperature and high-pressure metamorphic processes acting on the formations composed of igneous rocks.
At this early summer day, the midday sunlight was beautifully reflected as little stars in the flowing water. The pictured bedrock is very characteristic for the majestic fjord landscape in western Norway.
