----------------------------Original message---------------------------- Hello, all! I'm hunting for a public-domain source for major watershed boundaries for North America (US would do if it had to), in ArcView or MaPublisher readable format (DLG, ARC, MIF, etc), for a 1:20,000,000 scale. I'm not finding it in the obvious places. Any leads? -- Nat Case Hedberg Maps, Inc.
