|---|---|
| contact_certain | Boundary between two mapped units that retains the original depositional or intrusive relationship. The contact has been observed or is closely constrained, so it is well located as described in Positional_Accuracy. |
| normal_flt_certain | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault has been observed or is closely constrained, so it is well located as described in Positional_Accuracy. |
| normal_flt_inferred | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault is obscured by overlying mapped units and it's trace is uncertain, so it is not well located as described in Positional_Accuracy. |
| normal_flt_concealed | Structural boundary between mapped units or structural discontinuity within a mapped unit that has experienced relative offset between the rock bodies on either side of the fault. The fault is obscured by overlying mapped units and it's trace is fairly apparent, so it is not well located as described in Positional_Accuracy. |
| landslide_scarp | Line demarcating the headwall of a landslide, also serving as a contact between a landslide unit (Ql) and the adjacent lithologic unit. This feature has been well located as described in Positional_Accuracy. |
| basalt_flow_direction | Interpreted direction of lava flow as seen in a basalt flow unit. Arrowhead points in direction of flow. |
| map_boundary | Edge of the mapped area. Used primarily to bound polygons at the edge of the map database. The location of the boundary is well located as described in Positional_Accuracy. |

|---|---|
| fault_ball_fill | Arcmarker attached to an arc describing the nature of displacement along a fault. Side of arc with bar and ball is the side with downthrown displacement. |
| xx | No arcmarker is to be attached to an arc containing the xx value in the PTTYPE field. |
| Value | Definition |
|---|---|
| anticline_certain_red | The surface trace of the axis of an anticline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. |
| anticline_concealed_red | The surface trace of the axis of an anticline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. The axis is concealed by younger units but fairly apparent. |
| anticline_inferred_red | The surface trace of the axis of an anticline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. The axis is concealed by younger units and exact location is relatively uncertain. |
| monocline_certain_red | The surface trace of the axis of a monocline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. |
| monocline_concealed_red | The surface trace of the axis of a monocline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. The axis is concealed by younger units but fairly apparent. |
| syncline_certain_red | The surface trace of the axis of a syncline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. |
| syncline_concealed_red | The surface trace of the axis of a syncline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. The axis is concealed by younger units but fairly apparent. |
| plunging_syncline_red | The surface trace of the axis of a plunging syncline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. |
| plunging_anticline_red | The surface trace of the axis of a plunging anticline. The axis cannot be observed, but the location is constrained to be within about 5 mm at map scale or within about 16 meters on the ground. |
| map_boundary | Edge of the mapped area. Used primarily to bound polygons along the perimeter of the map database. The location of the boundary is well located as described in Positional_Accuracy. |

| bedding | Originally horizontal sedimentary layers were observed and measured at this location. |
| approx_bedding | Originally horizontal sedimentary layers were observed and estimated at this location. |
| collapse_structure | Location of a circular collapse structure characterized by strata dipping inward toward a central point was observed. May reflect collapse of a deep-seated breccia pipe. |
| sinkhole | Observed location of an enclosed depression or cave. |
| dome_red | Observed location of sedimentary layers dipping away from a central point. |
| vertical_joint | The orientation of vertical rock fractures without displacement was measured at this location. |

Prepared in cooperation with the National Park Service and the Bureau of Land management.
This digital database was prepared by Susan S. Priest. Technical review was provided by Dave miller and Johnathan C. Matti of the U.S. Geological Survey. Thank you to Jessica Wellmeyer and Debra Block of the U.S. Geological Survey Flagstaff Field Center for their GIS and ARC support. Digital review was provided by Scott Graham of the U.S. Geological Survey.
This geologic map of Clayhole Wash and vicinity covers the northern part of the Uinkaret Plateau of the Colorado Plateau geologic province of northwestern Arizona. The map is part of a cooperative U.S. Geological Survey, National Park Service, and Bureau of Land Management project to provide geologic information for areas within the Arizona Strip District of northern Arizona. This map fills in one of the remaining areas where uniform quality geologic mapping is needed. The geologic information presented will be useful for future resource management studies for federal, state, and private agencies.

Are there legal restrictions on access or use of the data?Access_Constraints: None
Use_Constraints:Spatial resolution.
Uses of this digital geologic map should not violate the spatial resolution of the map area (1:31,680) even though the digital data form removes the constraint of scale on a paper map. The accuracy inherent in map scale is also present in digital format. At a scale larger than 1:31,680, higher resolution data is not available and will not yield greater real detail. Where this database is used in combination with other data of higher resolution, the resolution of the combined output will be limited by the lower resolution of these data.
Any hardcopies utilizing these datasets shall clearly indicate their source. If users modify the data in any way they are obligated to describe the types of modifications they have performed. User specifically agrees not to misrepresent these datasets, nor to imply that changes they made were approved by the U.S. Geological Survey.
The U.S. Geological Survey (USGS) provides these geographic data "as is." The USGS makes no guarantee or warranty concerning the accuracy of information contained in the geographic data. The USGS further makes no warranties, either expressed or implied as to any other matter whatsoever, including, without limitation, the condition of the product, or its fitness for any particular purpose. The burden for determining fitness for use lies entirely with the user. Although these data have been processed successfully on computers at the USGS, no warranty, expressed or implied, is made by the USGS regarding the use of these data on any other system, nor does the fact of distribution constitute or imply any such warranty.
In no event shall the USGS have any liability whatsoever for payment of any consequential, incidental, indirect, special, or tort damages of any kind, including, but not limited to, any loss of profits arising out of use of or reliance on the geographic data or arising out of delivery, installation, operation, or support by USGS.
