Cobra Great

<p>Found less than 15 cm of new snow at the Moraine Lake road parking lot in the morning. Deepest (not windloaded) HN was 20cm near Annette Lake. Observed significant wind transport from the SW above 3000m from first light on Temple. At Lake Annette, we noticed that all north facing paths had avalanched in the last 24 hours with debris reaching 1/2 to 3/4 fan. Cobra Couloir had the largest debris, i.e. SZ 2.5 up to 1m deep covering nearly 3/4 of the whole fan. The crown of the avalanche could be observed at the very top of the couloir. Very little snow was left on cliffs above and on the sides of the Cobra. The couloir proper had an average of 30cm of soft slough debris in it with isolated November 8 crust pockets. Little trickle sloughs came down every 15 minutes or so with the bigger wind gusts on the neighbouring cliffs. No instability was noticed until 20m below the old crown where a 5-10cm thick 1F slab burried 20cm down gave an easy sudden collapse non-planar result on facets. We pulled the plug then and enjoyed great skiing down the couloir and on the loaded east side of the fan. No avalanche activity observed all day.</p>

Weather Report

<p>Wind transport could be observed on Temple's north glacier from the first light. Some small sloughs could be observed pouring over cliffs up high and dissipating under wind action before hitting any slope below. Wind remained strong all day above 3000m.</p>
