Remembering Alvin R McLane
died October, 2006 in Reno Nevada. An obituary is here. Without doubt Alvin was the
premier rock art researcher in Nevada. I went on many
rock art trips with Alvin and will miss him greatly. I
have put together a slideshow of my pictures of
Alvin. At NAA in Ely, Nevada I gave a presentation on Alvin's last road trip.
At the 2007 ARARA meeting in Billings, Montana I gave a
presentation on Kachina
Rockshelter, a place I
visited with Alvin on the trip. Alvin and I intended to
write a paper on the sites we visited.
