[Sasnet] obsidian from sources in the British Columbia region

[Glascock, Michael D.]

I recently analyzed several obsidian artifacts from British Columbia for
a colleague.  But, I was unable to determine sources because I am
lacking reference samples from most of the sources.  If anyone has
source materials from British Columbia to spare and will allow me to
analyze them to improve my obsidian source database (NAA and XRF), I
would be very appreciative.    Known or suspected sources for which I
have need of samples are:

1.       Mount Garibaldi (outcrop is about 15 km northeast of Squamish)

2.       Mount Cayley (obsidian occurrence and location are uncertain)

3.       Twin-1 (outcrop is 1.5km northwest of Upper Twin Lake)

4.       Various subsources of Mt. Edziza (a very complex major obsidian
source in this region)

 

Sincerely,

Michael D. Glascock
