Conifer Tree Rings


Cross-section of Lodgepole Pine (Pinus contorta latifolia)
Location:  Rocky Mountain National Park, Colorado, USA

This is the top of the stump of a Lodgepole Pine (Pinus contorta latifolia) that had just been cut down by staff members in Rocky Mountain National Park. The tree's annual growth rings are clearly visible.  I thought the variations in coloration were interesting.
