ATLAS MAP 3: GEOLOGY-LAND USE 



The Geology-Land Use maps were compiled from a variety of sources and 

 represent many different data types. Certain data are the results of complete 

 inventories and others are the results of localized studies (e.g., surveyed 

 peat bogs). Each data type included in atlas map 3 is described below 

 preceded by the map symbol used to identify it on the map and the source of 

 information.
