Summary If there is good reason to believe that the collections (59ALy-240, -271, and -276) reported on here all came from the same rock unit, the formation is probably of middle Paleozoic (Devonian or Silurian) age. Two of the collections (59ALy-240 and -276) contain fossils that, though very poorly preserved, are suggestive of Siluro-Devonian faunas as known in Alaska. Nothing identifiable was found in lot 59ALy-271, but the lithology, as revealed in thin sections, seems to be much like that of lot 59ALy-240.
Lot 59ALy-276 was studied by Dutro and is being retained here. The other two collections were examined by Duncan. These lots together with the thin sections are being sent back to you.
