7 14 Contact Fault Folds-Showing trace of axial surface and direction of plunge; dotted where concealed Strike and dip of beds Landslide scarp-Headward scarp of landslide; hachures point in direction of slide Inclined Strike of vertical and subvertical joints Sinkhole Collapse structure-Circular collapse structures characterized by strata dipping inward toward the central point. May reflect collapse of deep- seated breccia pipe that originated in Redwall Limestone Flow direction of basalt Pyroclastic cone Syncline -Dashed where inferred or approximately located; dotted where concealed; bar and ball on downthrown side. Number is estimated fault separation in meters, number in parenthesis is estimated displacement of indicated units along fault -As indicated on aerial photos -Measured in the field -Enclosed
