Tree climbing graphics. The Klukwan giant holds the national record for black cottonwood diameter. Jul 23, 2021 ยท A tree near one of our campsites had a crack at its base through which we could pass the folded saw. Photo by Sara Wilbur A gray-headed chickadee feeds along the Canning River in northern Alaska in 2015. One tree, of course, proves nothing. Yet the tree was still alive, with just one rope of cambium — the outer bark that transports water and nutrients — snaking up the trunk. Each spring, small yellow pustules appear on the new needles of the broom. A strong sweet odor, which is easily recognizable, usually accompanies the maturation of these pustules. Witches' broom on spruce trees is caused by a rust disease (a kind of fungus disease). A few of its blue-green feathery leaves flagged from the top of what otherwise looked like a snag. Burls, spherical woody growths on the trunks of spruce, birch and other trees, are commonly found throughout wooded parts of Alaska. itsqar bpq6qu w57p 2snqc 8q rmm 7zvrt 6btf wzo4 m6b
