The Tallest Saguaro is now only a footnote in history.
Art Dorner of Sun City AZ reported, “I’m sorry to say that the tall saguaro cactus fell over on or about December 6, 2007. It was a beauty and I visited it many times,” in a comment to Allan Hall’s article, “The Spring Flower Show of 2005” posted on this web site.
It was a sight to behold, a magnificent towering desert sentinel standing guard near the mouth of Unida wash where it enters the Hassayampa River. The height was estimated to be 50-1/2 feet reported by Dana Burden, ref . Dennis Orr and I estimated the height to be 56 feet during our visit in April 2007. Actual tape measurements made during our December visit showed the height to be slightly less than 46 feet with a 7 foot circumference at the base and thus perhaps not the tallest after all.
Saguaros die from several causes: frost, winds, bacterial rot, and vandalism. In most cases the cause is freezing which damages the soft tissues thus starting the rotting process. If unable to protect healthy tissue, the decomposition spreads until its death, though the saguaro may continue living for several years after the onset of the damage, ref .
In this case, it was evident that most of the cactus was consumed by rot, showing black tar-like fluid oozing from various parts. It appeared one major arm broke off first, weakening the supporting structure and causing unbalance, allowing the main trunk and remaining arms to fall in the opposite direction.
To think that such a towering giant started life from a seed the size of a pinhead – just only one to successfully germinate and grow from the thousands produced each year. Conditions for germination and the early growth years are nearly exacting: right location for soil conditions, protection, moisture and warmth, ref . If successful during this period it will continue to grow around one inch a year and reach heights from 15 to 75 feet and live as long as 200 years. The conditions for this beauty were obviously good: remote and well sheltered in a wash with access to plenty of water. Its age is estimated to be well over 100 years.
