EXPLANATION OF MAP SYMBOLS

Contact—Contacts between all alluvial and eolian units are approximate and 

arbitrary

Fault—Dashed where inferred or approximately located; dotted where concea

bar and ball on downthrown side. Showing fault offset in feet

Fracture—Open fracture (1 to 12 ft wide) without offset

Folds—Showing trace of axial plane and direction of plunge

Anticline

Syncline

Plunging syncline

Monocline—Axis at approximate center of dipping limb

Dome

Strike and dip of beds

Inclined—Showing dip measured in the field

Implied—Interpreted from aerial photographs; dip not determined

Strike of vertical and subvertical joints—Interpreted from aerial photograph

symbol placed where joints are most visible on aerial photographs

Collapse structure—Black dot shows circular collapse structure characterized 

strata dipping inward toward a central point. Magenta dot shows circular 

collapse structure characterized by strata dipping inward toward a central 

point and brecciated rock
