White Pine

Elevations, slope angles and aspects

7800-11k, angles over 35°, north, east and west facing aspects.

Snow conditions

Refreeze was marginal.

Snow at lower elevations was spongy and supportable in the morning.

Surface crust gradually thickened with elevation gain, becoming firm above about 10k(still edge able).

Northwest facing stayed cool into the afternoon, ene warmed enough to initiate wet activity by noon,

lake-peak

limited to rollers.

Weather

Overcast to foggy skies. Upper elevation cloud deck kept the peaks obscured with only occasional views.

tanners-clouds

Spits and sputters of rain below 9k, snow flurries above, little accumulation.

Wind from the west, gusting over 20 mph at upper elevations.

Evaluation

Stable in the am, increasing instability with daytime heating.

Weather guess is for rain below 9k, snow above.

Stability would be dependent on bonding of new snow to old surface above the rain-snow line.

Wet activity is likely to increase below snow line.
