The specimen is wood of spruce, Picea. This extant genus occurs in both Upper Cretaceous and Tertiary rocks; consequently, they cannot be differentiated by this fossil form.

Brief statement of problem and remarks (from collector):
Pieces of fossil wood showing well-preserved growth rings and cell structure were found in and obtained from a thick section of siliceous tuffs and breccias of unknown age. I hope that study of the specimen will indicate whether the volcanic rocks are of Mesozoic or Tertiary age.
