The Bristlecone Pines of Mount Evans
Most pine trees shed their needles yearly. The Bristlecone in contrast only sheds its needles every 10 to 15 years. It also is very slow growing. Its narrow growth rings create a very dense wood that is hard for pests to penetrate. It is also makes the tree slow to decompose. Centuries after death, the Bristlecone can remain standing, a mute testament that man's hubris. The Pyramids were raised and will crumble long before the average Bristlecone Pine turns to dust. If you are looking for a fast growing privacy tree, don't look for a Bristlecone!

There places to bump into Bristlecone Pines along the Front Range. Many of the hikes in the Mt. Evans area including Chief Mountain and Chicago Lakes have them. I was surprised to run into a stand of them up Mt. Royal near Frisco. The photos in this post were taken on Mt. Evans at the Mount Goliath Research Natural Area. There is a short interpretive trail through the trees as well as a 3-mile trail (Pesman Trail) that really lets you get up close and personal to the "ancient ones".
While some Bristlecones have been dated to 4,900 years old, the oldest on Mt. Evans is only 1,750 years old. Quite young by Bristlecone standards. Perhaps that is why there were so many beer cans laying around the base of the trunks. These Bristlecones are in their late 20's.

Not all Bristlecones possess the twisted shape that identifies them to most people. That is an adaption for life near treeline where the conditions are the harshest.
The forest service does a talk on the Bristlecones every day at noon during the season at the Dos Chappell Nature Center, which is 3 miles up the Mt. Evans road from the fee station. Entrance to the Mt. Evans area is now covered by the standard Federal Lands/Parks Pass ($80/year), so you have no excuse not to visit.
