I forgot to mention Kudos to Dave Parr.
He held an impromptu local Geology course Friday morning during the 2 hours set aside for coffee get together. It was very interesting and informative. Fred, Nancy and I went looking for Thompsonite rocks which the area is known for. Later we had Dave peruse through our findings to make sure we had what we thought we had. He also identified other rocks we picked up.
Thanks again to Dave
