Abstract Non-permineralized or mummiWed ancient wood found within proglacial soil near the ad Astra Ice Cap (81°N, 76°W), Ellesmere Island, Canada was investigated to ascertain the identiWcation of the trees, current morphological and chemical characteristics of the woods and the fungi within them....
