does anyone have a method to identify topographic lineaments from a DEM?

most dems are not terribly high resolution.  I think you would have a difficult time finding a lineament on one.  You might have better luck with a high resolution Air Photo.

If you have the proper extensions (3D Analyst) you could create contours from the DEM and try to use that to determine lineaments.

If you happen to have Lidar data available for your area that  might be a better bet.
