Abstract:
This data set represents GIS coverages of the Castle Mountain Fault captured from three maps representing portions of the fault in south central Alaska.
Purpose:
Provide land managers with an authoritative source for the location of the fault in the Talkeetna Mountains and Susitna Lowland. Digital maps may be displayed at any scale or projection, however the geologic data in this coverage is not intended for use at a scale larger than 1:63,360.

Native_Data_Set_Environment:
Data set was created using ESRI ARC/Info version 7.2.1 on a Unix platform.
Data_Quality_Information:
Attribute_Accuracy:
Attribute_Accuracy_Report:
Data attribute accuracy is tested by manual comparison of the source with hard copy plots and/or symbolized display of the map data on an interactive computer graphic system. Selected attributes that cannot be visually verified on plots or on screen are interactively queried and verified on screen.
Logical_Consistency_Report:
This data set contains line coverages with arcs that represent faults, linements, or anticlines. Each arc has been assigned a code that indicates what type of feature it represents.
This data set also contains point coverages that represent high and low elevations along the fault.
Completeness_Report:
This data set is comprised of only the faults or elevation points from each source. Other information about the geology such as contacts between units or points without elevation values was not included.
Positional_Accuracy:
Horizontal_Positional_Accuracy:
Horizontal_Positional_Accuracy_Report:
The data from the Detterman and others (1974) map should be considered less accurate than the data from the other maps.
Users of this digital geologic map should respect the intentions of the original mappers and the limitations of the map. This geologic map compilation is intended to be used at a scale of 1:63,000; it is not intended to be used at a more detailed scale.

Process_Step:
Process_Description:
The Haeussler (1998) map was the easiest to include in this compilation since it was already available digitally. Because of this the attributes from the Haeussler (1998) map were used as the basis for assigning attributes to the arcs from the other coverages. The data from the other two sources was captured by hand digitizing from folded paper maps on a GTCO digizizer into ARC/INFO coverages.
The Detterman and others (1974) map was comprised of three unregistered aerial photographs with the fault and point locations drawn over them. In order to georeference the data it was digitized in straight table coordinates, and then registration points were established between the photographs and georeferenced images of USGS topographic maps. Due to the lack of prominent features on the photographs the registration points could not be located with as much precision as desired. To compensate for this the faults and points were rubber sheeted to the images of the topographic maps after registration. However, the locations of these faults should still be considered less accurate then those from the other sources.
The Detterman and others (1976) map drawn over a topographic base, so it could be registered without accuracy problems. All faults on the map were digitized.
Where there was overlap in between the three sources the Haeussler (1998) map had priority. In two cases fault positions were adjusted to connect with faults from the Haeussler (1998) map.
One anticline was included from the Saltus et al. (2001) map.
Together the modified fault coverages and the data from Saltus et al. (2001) comprise the coverage cmfault.
The unmodified versions of Haeussler (1998), Detterman and others (1974), and Detterman and others (1976) can be found in cmfault_c, cmfault_w, cmfaultw_pnt, and cmfault_e respectively. The data from Saltus et al. (2001) was not modified, so it does not appear in a seperate coverage.
The arcs and points were then attributed in ARC/INFO. For the purpose of distribution, the coverages have been converted to an interchange format file using the ARC/INFO export command.
