Evergreen under White
Despite a raging blizzard the previous day that seemingly should have blasted any and all accumulations off these limbs, they collected snowflakes anyway. The answer to this seeming mystery is found first in a constant wind direction, second in sheltering. The leeward position of these limbs, and the middle position of this tree amongst a grove of several, allowed relatively tranquil air to drop snow essentially vertically for a sustained period. The wind, though gusting over 50 mph, somehow didn't slam the other side of the sturdy cedar hard enough to throttle all the snow off this side, either.
