Summer growth at Logan Pass
by Chiara Arrighi, University of Florence, Florence, Italy
At Logan Pass (Montana, US) the snow melt favours an extraordinary summer growth of hundreds of flower species. In this picture you can see the red monkeyflower under the sedimentary rocks of Clements mountain.
Geologic formations in Glacier National Park are recognizable by dramatic exposures of Precambrian age Belt series sedimentary rock. These ancient rocks record a shallow Belt sea environment that opened and closed intermittently over many millions of years. The origin of Belt series sedimentary rocks dates from about 1,600 to 800 million years ago.
