Contact—Contacts between all alluvial and eolian units are approximate

Fault—Dashed where inferred or approximately located; dotted where 

concealed; bar and ball on downthrown side. Number is estimated 

vertical fault separation in meters

Folds—Showing trace of axial surface and direction of plunge; dashed 

where approximately located; dotted where concealed

Anticline

Plunging anticline

Syncline

Plunging syncline

Monocline—Axial trace located along steepest part of monocline

Dome

Strike and dip of beds

Inclined—Measured in the field

Implied—Interpreted from aerial photographs; dip amount not determined

Strike of vertical and subvertical joints—Interpreted from aerial photographs; symbol placed where joints are most visible on aerial photographs

Collapse structure—Circular collapse structure characterized by strata 

dipping inward toward central point. Collapse area may reflect deepseated breccia pipe that originated in Redwall Limestone 

(Mississippian; not exposed at map surface)

Breccia pipe—Collapse structure characterized by visible breccia rock 

column within area of circular inward dipping strata

Sinkhole—Enclosed depression or cave. Sinkholes breached by drainages 

are not shown

Volcanic vent or pyroclastic cone

Copper mine

Uranium mine

Flow direction of basalt
