Horsetooth tree stan

Yes, I mean stan, not stand. One quarter mile below the top of Horsetooth's Spring Creek Trail, at 6770 feet elevation, there is a gnarly old Douglas fir that has grown up against a large boulder that rolled to rest in the drainage long ago. The trail goes right under it and I love pointing the tree out to people who've never noticed it before.

This tree deserves a better photo

One day I'm going to bring my better camera up there along with some cord to measure the tree's circumference. I estimate its diameter at breast height (dbh) to be almost 36 inches. Some formulas for estimating the age of a Douglas fir say to multiply the diameter in inches by 5 to get the age of the tree in years. Rocky Mountain Douglas fir grow more slowly than trees in the Pacific Northwest and grow extremely slowly after 200 years. Is this a 180 year-old tree or is it older? I haven't noticed a larger or more lichen-covered specimen anywhere in the park.

Bark, lichen, and stone

I'd love to know more about this tree. Please Send me an email if you know anything about its history.
