Digital fold axis data for Oregon?
For some time, I've been wanting to look at the relationship between landslide distribution and structural features of our study region. I'd been thinking I'd look at proximity of landslides to fold axes, because it was fixed in my mind that digital fold axis data exist for Oregon, whereas digital strike and dip data do not. However, when I sat down to start figuring out how to do this analysis, I could find no such data. I plumbed the metadata and coverages associated with the 1991 Walker and MacLeod 1:500,000 map, as well as the info about the latest DOGAMI digital geology compilation. Nothing. Did I just fabricate this idea that fold axis data exist?? Does anyone have or know of digital data for central/eastern Oregon that might give clues about stratigraphic attitudes (there's a bit of info about fault plane dips, but that's all I could find)?
