 a cliff of horizontal Animikie indurated shales, 

 150 feet (45-7 m.) high. The Animikie-Ar-

 plastered on horizontal surfaces of the granite 

 gneiss. But the structural discordance between

 which outcrop a short distance away, is sufficient 

 proof of uncomformable relations. 



From this locality westward

 with this belt are lenses of iron formation 

 which constitute what is known as the Mattawin 

 iron range. The iron-formation is generally 

 banded in character, and deposits of clean ore
