On the guessings, I hate saying it, but all wrong.

I used a combination of USGS DEMs, Photoshop v6 Cloud Renders, A LOT of touch up in Paint Shop Pro v8. I then ported the two layers into ArcGIS and did the hillshading and color relief render in ArcGIS. Then ported it back into Photoshop, turning the transparency of the color relief down enough to get the hillshading to show through.

A lot of patient work and it does take some time.
