Remembering Alvin R McLane
Alvin
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 ARARA 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.
