H. Wood — Cretaceous of 'Northwestern Montana. 401 



That, as the meteor struck our atmosphere, the concussion 

 was so great that the mass was fractured in various places, of 

 course extending from the surface inward, and the larger of 

 these fissures or fractures were then filled by the metallic iron 

 which was fused on the exterior surface of the mass, clue to its 

 velocity through the atmosphere, and was thus forced in a 

 molten state into its present position, thus forming the metallic 

 veins.

(i natural size.) 



I have attempted to obtain the Widmanstatten figures on 

 the largest nodule of iron in the mass, but thus far have been 

 unsuccessful.

The geographical position of the Flathead Coal Basin is 

 indicated by the accompanying map, it being a continuation 

 southward of the Flathead Valley, south of the North Koo- 

 tanie Pass, the Elk River and Crows' Nest Basins* in Southern 

 British Columbia or more particularly Alberta Province. It 

 is the inter-mountain Cretaceous which forms the connecting 

 link between the Cretaceous of British Columbia and Tobacco 

 Plains to the northwest and the Sand Coulee, Bozeman and 

 Rocky Fork Cretaceousf east of the main range or Rockies
