A two-week old buried weak layer still exists on protected mid and upper elevation northerly to easterly facing slopes. This is buried 1-3' deep and may be triggered at a distance. The last reported collapses was on Friday and was the culprit in a very close call on the 25th. In suspect terrain, a quick 2-3 foot pit could reveal the thin grey line or the alarming test result that keeps you out of harms way. Weak interfaces may also be found before this last storm at the mid and upper elevations (see Scrapey's avalanche). Extra caution is recommended in this suspect terrain. Obvious clues may not be present.
