Big Chunk of Cedar Lake Amber
Cedar Lake amber at the Manitoba Museum, Winnipeg, Canada.
Largest piece is 2 inches! or 5 cm across in with the woody debris when / where typically found. The lot on the right are larger than average. Perhaps one in ten specimens contain insects. Geotagging shows my guess as to the original beach site, submerged for decades by a dam, with some amber now said to be resurfacing.
