Short tour in the Bishop Creek drainage to look at snow and weather conditions.

Evidence of many wet slides on E-NE aspects of Table Mountain (see photos).  Most of these slides appeared to have happened within the last 24 hours with start zones (thsoe that were visible) fairly low 9000-9500 ft. 

1015am: 8400 ft- South Lake Rd parking. Strong SW winds.  Light rain.  Air temp=10C. Snow on road cuts at parking lots ~1m deep, moist throughout profile.

1120am: Skinned up road.  Cloud ceiling ~10,500 ft.  Could not visualized cornice or snow transport over ridgelines. Snow surface moist. Moist to about 80cm depth.  Ski penetration=5-10cm. Air=6C

1230pm: ~9500 ft. Continued strong wind.  Snow surface moist to 40cm depth.  Ski penetration 10-15 cm. Dense but generally dry below that. Rain has turned to light snow, usually melting on contact. No snow accumulation noted.

1pm: 10,300ft. Strong, gusty winds transporting snow. Snow surface pencil firm (2cm thick), moist crystals noted in this layer. Dense, dry snow below that. Ski penetration 0-2 cm.  Air= -1C.
