These ancient bristlecones are two of the more iconic in the world. They stand on an eastern slope in the White Mountains in a clearing with few other trees nearby. I am fairly certain the foreground tree — which has been photographed by thousands of photographers — is dead. It has a beautiful, gnarled, twisted shape and is quite imposing. The living bristlecone (Pinus longaeva) in the background is my favorite in this area, and one of the most beautiful of the old but living bristlecones anywhere along the White Mountains crest. It was the subject of the first milky way photograph (after many attempts) with which I was really happy, made alongside buddy Garry McCarthy in 2012. The evening I made this particular photographs brought a fast changing mix of light, with clearing storm clouds that alternately moved through the scene and then opened up to reveal stars. I timed my visit specifically for this one night since I knew the lunar phase would balance moonlight with starlight and lend a little bit of detail to the surrounding landscape, something that is more difficult to achieve on the new moon. I’ll post a few more from that night in the coming days. Cheers and thanks for looking!

Ancient Bristlecone pine trees (Pinus longaeva) live in a relatively restricted area of eastern California, Nevada and Utah, typically at altitudes above 9500′. The ancient bristlecone pine tree is considered to be the world’s oldest species of tree (and indeed the world’s oldest sexually reproducing, nonclonal lifeform). A number of individual bristlecone pine trees are known to exceed 4000 years of age; the “Methuselah tree” in the Schulman grove was estimated to be 4838 years old in 2006. These extraordinarily hardy, gnarled and lonely trees are best seen in the White Mountains of the Inyo National Forest in California. These photos were taken in the Patriarch Grove and the Schulman Grove, two exemplary groves that can be accessed by car. A few new images below and in my gallery of bristlecone pine tree photos were taken on a clear spring night with the Milky Way spread across the sky — it was a moving and serene experience being around such old trees with the heavens spread so dramatically above.

Ancient bristlecone pine trees live at extremely high altitudes. In some regions, the lower treeline for bristlecone pines exceeds the upper treeline for all other species. Bristlecone forests often occur in areas where there is a strong carbonate content (limestone, dolomite and/or marble). In these barren, remote mountain areas, exposure to constant wind, excessive sun and bitter cold has molded the trees into remarkably gnarled, twisted shapes that have captured the interest of photographers and artists for years.

The trees do not grow tall — 60′ is about the tallest — but tend to be girthy with a wide base and roots that splay outward in all directions. Ancient bristlecone pine trees grow very slowly, and pine needles are infrequently dropped with some living for 30 years. Pinus longaeva has evolved a few strategies that yield such a long lifespan. Their wood is extraordinarily dense, and full of resin, making it nearly impossible for invasive bacteria and insects (what few there are in that inhospitable climate) to bore into and damage the wood. Bristlecone pines also tolerate a gradual dieback of their bark, in such a way that old specimens may have only a small amount of living bark. While the tree may appear dead or nearly so, this is actually an advantage as it lessens the bulk of living material the root system and crown must support. In some old trees, a thin strip of bark a foot or less in size is enough to support a healthy specimen.

Ancient bristlecone wood is so resistant to decay, and occurs in such an arid and cold environment, that fallen pieces dating back 8000+ years have been found in some groves. These pieces have been used in the calibration of the radiocarbon time-dating method, a technique which is employed in a broad range of scientific disciplines.
