Mr. McCall performed stability tests in a snowpit at about 11,300 feet — the snow was about 30 inches deep, with depth hoar and uncohesive snow making up about the bottom third. |
The ice was a little slow however, as it had hoar frost on it from the humidity in the air that morning. |
The strength of a layer of depth hoar is very low and the structure of the layer falls at the slightest touch. |
Snow covers the village in Sisley's Winter at Louveciennes, the slanting shapes of three passers-by drawing the eye to the twisted trunks of fruit trees on which a hoar frost hangs like wintry blossom. |
A heating element mounted on each transceiver prevents the formation of condensation or hoar frost. |
The avalanche appeared to be the wind loaded storm snow running on the old surface hoar layer. |
