Dinosaur Douglas Fir

Rocky Mountain Douglas-Fir (Pseudotsuga menziesii var. glauca)

About this verified tree

Very large Douglas-fir in the Porcupine Hills, a true giant for its location. This tree is one of the largest in the area and is most definitely among the oldest trees locally. Comparing this tree to others of similar size and growing conditions, has lead me to believe this tree is no less than 500 years old, probobly more. This is a prime example of old-growth Rocky Mountain Douglas-fir on the prairies of Alberta, which is not common. In fact, trees of this size are few and far between in our province. Well... except here. Nothing in Banff, Jasper, Waterton, or along the Oldman River reaches the almost coastal sizes of the dougies in the Porcupine Hills. I wonder, whenever I pass by on Highway 22, just how many ancient prairie giants have been felled over the years in those hills. Douglas-fir was heavily sought after during the colonial and settlement periods, especially around these parts. Almost none of the local timber in southern Alberta could provide the massive amounts of lumber that cutting old-growth Douglas-fir yielded. I think there are 6.5-metre-plus circumference trees waiting to be discovered in the Porcupine Hills.
