Notes
Cow Valley area, central Oregon. Notes from Dr. Scott Singleton, Houston Museum, 2005: Sequoia Family: Taxodiaceae central Oregon Formation: Age: Miocene or Pliocene Distinguishing Characteristics: Pronounced growth rings resulting from seasonal temperature variations in a temperate environment. The growth rings are more evident in sequoia (and its cousin, cypress) because of the abrupt change from very large cell size in the early wood (known as coarse texture) to very small cell size in the late wood. This phenomenon is termed uneven grain, and is more extreme in sequoia and cypress than in any other conifer, making this feature of critical importance in identifying these two genera. Because of this growth characteristic, sequoia makes a good candidate to slice longitudinally. The resulting plank reveals dramatic weaving lines as the cut intersects each growth ring, making this an interesting variation to the usual transverse (cross-section) cut.
