Last week it took 4 guys with trucks, saws, ropes, and a cherry picker to take down my giant dying Beech tree in 4 days. Not to mention a lot of $.
Last night, a damp heavy snowstorm took down a White Pine in an instant, around 4 AM. The quick way to down a tree. The boom woke me up. The main trunk missed my shed by 3' and missed my car by less than a foot, and somehow missed my flag. I uttered a Thanks to the Snow Goddess. It did knock down my fence, though.
White Pine is a fast-growing, brittle tree. It's best kept far from things that matter. Terrible landscape trees. This was about an 18" diameter main trunk, which snapped around 10' above the ground. Photo is (was) the top of the tree.
