Notes
~4-5 million years Oregon/Prineville, Crook Co.,central Oregon. Notes from Dr. Scott Singleton, Houston Museum, 2005:Soft Pine Genus: Pinus Family: Pinaceae (Pine) near Prineville, Crook Co., central Oregon Formation: Age: Pliocene, ~4-5 million years Distinguishing Characteristics: Growth rings apparent but not dominant. This is because there is only a small change in cell size between earlywood and latewood. This is in contrast to the Hard Pine subgroup that has a distinct difference in cell size through the growth ring. Pines are distinguished from other conifers by the presence of large, single resin vessels scattered throughout the growth ring. Environment of Deposition: The Pliocene is characterized by a continued cooling and decrease in summer rainfall from the previous era (Miocene). The Pliocene Cascade rain-shadow flora of eastern Oregon was a low-diversity, riparian vegetation of deciduous hardwoods (meaning the hardwoods grew along bodies of water) that were bordered by scrubland. Common genera were maple, poplar, oak, willow, and elm. Original deposition was either as rafted material in rivers or waterlogged material in lakes. These environments were repeatedly covered by basalt flows or ash falls from Cascade volcanoes. When entombed by molten basalt, these trees burned unless they were covered by water in a stream, lake, or swamp. Ash falls offered an opportunity for these forests to be preserved in their upright, in-situ positions by large quantities of relatively cool ash.
