Overview of attributes

'Unit' is a numeric item in the polgon attribute table for
coverages east and west.  The attributes have the following
descriptions:
>1 	Qp	Peat deposits (Holocene)
>2 	Qg	Basal drift of Elemendorf advance (Pleistocene)
>3 	Qac	Abandoned river channel deposits (Holocene or Pleistocene)
>4 	Qc	Undifferentiated colluvium (Holocene)
>5 	Qgb	Thin drift of Elmendorf advance (Pleistocene)
>6 	Qad	Ancient drainage deposits of Elmendorf advance (Pleistocene)
>7 	Qat	Alluvium in river terraces (Holocene or Pleistocene)
>8 	Qaa	Alluvium along rivers (Holocene)
>9 	Qml	Lateral moraine of Elmendorf advance (Pleistocene)
>10	Qas	Undifferentiated colluvium and alluvium (Holocene)
>11	Qk	Kame terrace deposits of Elmendorf advance (Pleistocene)
>12	Qg2	Drift of pre-Elmendorf advances (Pleistocene)
>13	Qat2	Alluvium in paleodrainage (Holocene or Pleistocene)
>15	Qam	Alluvium along small meandering streams (Holocene)
>16	Qls	Landslide deposits (Holocene)
>17	Qe	Esker deposits of Elmendorf advance (Pleistocene)
>99	w	water
The arc attribute tables for the coverages east and west have
a numeric item named 'code', which has the following
descriptions:
>0 	leader
>1 	contact
>2 	contact
>3 	contact, approximately located
>9 	water boundary
The arc attribute tables for coverages fault_e and fault_2
have a numeric item named 'code', which has the following
descriptions:
>1 	fault
>2 	fault, possible location
>3 	fault, approximate location
>4 	fault, concealed
>5 	fault, probable location
>6 	limit of aerial photograph coverage
>7 	lineation, probably reflecting bedding in underlying bedrock
