Last I heard, Katie Lee was living in Jerome, AZ. I sang with her at the Limelite in Aspen, CO, back in the summer of '59. Learned "Ten Thousand Goddam Cattle" then. We've kept in touch off and on ever since. She has several cassettes available. I think she'd also insist that Ian Tyson should have sung "Sirey Peaks," not "Sierra." She's a stickler for authenticity, bless her soul.
Harry Tuft recorded a nice "Old Dolores (The Town of Old Dolores)" on his Folk-Legacy album, which will appear as a CD in a couple of weeks. Ed Trickett recorded "The Telling Takes Me Home" (it's the title song of his first Folk-Legacy recording, now on cassette), and Utah recorded it himself on a similarly titled release.
Another great song is Slim Critchlow's "The Last Wagon," which is on For All the Good People, A Golden Ring Reunion (Folk-Legacy CD-121).
