Description
English: Dead trees in the terraces of Mammoth Hot Springs, Yellowstone National Park, Wyoming, US. These trees grew during inactivity of the mineral-rich springs, and were killed when calcium carbonate carried by spring water clogged the vascular systems of the trees. The same process also effectively preserves the trees by preventing decay. (A 2×1 panorama).
Français : Arbres morts sur les terrasses de Mammoth Hot Springs, dans le parc national de Yellowstone, dans le Wyoming (États-Unis). Ces arbres ont poussé avant que la source ne les atteigne, puis ont été tués quand la calcite transportée par l'eau a obstrué leurs vaisseaux. Ce même processus préserve le bois du pourrissement. Panorama issu de 2 clichés.
