Singleshot Mountain Morning
The view as I left the St. Marys Campround just at sunrise headed to Logan Pass in Glacier National Park, Montana. Even in the early light one can see the gleaming white of quartzite which is interbedded with the grayish green argillite and silttite. These beds in the top top of the mountain are called the Appekunny Formation and overly tan dolomites and limestone of the Altyn Formation which make up the lower visible rocks on the mountain. Both rock units are Middle Proterozoic in age (with the Altyn being the oldest (1.6 billion years to 1.3 billion years old) of the Proterozoic rocks in Glacier.
