Pinus washoensis

The stands of Pinus washoensis on the Warner Mts Modoc County, California. These stands merge with Pinus ponderosa ssp. ponderosa at lower elevations. Pinus washoensis is only clearly recognizable at the highest elevation. In between are all kinds of intermediates. Cones were collected at increasing elevations, starting at bottom to the top. Last summer, most of the thousands of acres stand burned. 1 1 Pinus washoensis - Trunk One of the largest Pinus washoensis seen from the road. The bark is similar to Pinus ponderosa ssp. ponderosa, but appear more reddish color instead of the yellowish plates of ponderosa. In some ways, it looks more like the bark of Pinus jeffreyi with the reddish color and dark almost black fissures. Warner Mts.
