| Description | The geology of the Salmon National Forest, Idaho, was compiled from published and unpublished sources and new field mapping by Evans, Lund, Tysdal, and Winkler between 1997 and 2001. The geology was compiled onto 1:100,000-scale topographic base maps for |
| Originators | Evans, Karl V.; Lund, Karen I.; Tysdal, Russell G.; Green, Gregory N.; and Winkler, Gary R. |
>Attribute items are in ARC/INFO feature class format. Additional >items that were added to the data are: > >POLYGON > >attribute description >========= =========== >acc_val Acceleration value in percent of gravity of the > polygon. The polygon represents the range of > acceleration values that are contained within its > borders. The polygon is assigned the lowest value > allowed within the polygon's borders. The range of > values allowed within a polygon is controlled by the > contours. Valid values are: 0,4,8,12,16,20,24,28,32, > 36,40,60,80,100,120,160,240,320,400 > >valley A topological indicator that tells whether the area > contained within the polygon is a local minima (valley) > or not. A value of "1" indicates the area is a local > minima. >LINE > >attribute description >========= =========== >acc_val Acceleration value in percent of gravity that the > contour represents.
