This is the event that replaced the Oregon Ridge Primitive Technology Weekend, an event that ran for 20+ years. It's now held at Willow Grove Nature Center (Cromwell Valley Park) in Baltimore County north of Baltimore, MD. It's a great event- you get to rub elbows with both career archaeologists and avocational primitive skills practitioners, plus it's free! Here's the link (this year's agenda is here, as well) http://www.cromwellvalleypark.org/events.html
Thanks for putting up the information.
Looks like the Mistassini Quartzite, to be discussed, had a significant geographic range, despite it's scarcity
