Avalanche: Mill B South

While hiking to Lake Blanche I observed this avalanche just below the lake. It appears that the avalanche started in the rocks above (note the fracture line in the snow in picture). The avalanche then propagated down the steep slope leaving a fairly significant deposition pile at its terminus. From my location, it appeared to be perhaps 5 - 10'+ deep (see next pictures). The avalanche likely occurred prior to last weekend's storm as new snow was observable on the avalanche proper.
