In 1915, Thoralf Vogt tavelled along the eastern margin of the Caledonian mountain range from Tornetr\u00E4sk in Norrbotten through Troms (Norway) and the adjacent regions of Sweden and Finland to Nordreisa (in the north-easternmost part of Troms). A preliminary report on the results was published in Norsk Geologisk Tidsskrift no. 4, pp. 260-266, 1918. Professor Th. Vogt died in 1958. In December 1966 a draft of a broad account was found among his papers at the Geological Institute of the Technical University of Norway, Trondheim. As the chapters treating of the \"Hyolithus zone\" (or Dividal Group) turned out to be very nearly ready for publishing, and their contents are of great current interest, the directors of the Geological Survey of Norway - in agreement with the director of the Geological Institute of the Technical University - decided to have these chapters printed in the form of the present paper. Th. Vogt gives a statement of the stratigraphy of the \"Hyolithus zone\" (Dividal Group) and describes a large number of localities. A geological map and a plate containing a columnar representation of 23 sections acompany the paper. The sequence consists of approximately flat-lying beds, mainly of Lower Cambrian age, resting on a basement of Precambrian crystalline rocks.
