Here is a quick revised plan (as of Tuesday march 31, 2015) ...

Friday
    -Meet at St. Davids Friday morning 8AM.
    -Walk/skin up to Elfin Lakes hut.
   - Have lunch + some yo yo ing + dinner + bed
 

Saturday
   - get up early and head out (we can either go up towards Little Diamond Head or down into Ring Creek).
   - Make a 'valiant' effort to bag Dalton Dome (subject to good avi and crevasse conditions).
   - Return to the cabin + dinner + bed

Sunday
   - Return to the vehicles.

If the weather forecast is bad, I will change the plan or cancel altogether.  I will make the decision tomorrow (Wed.) night. 

It looks like some people may want to tree ski and stay down off the glacier (this may include myself as I have had some injury issues). Let me know if this is the case, so I can plan ropes and gear.

The cost of the Elfin hut is $15 per person per night.  I will send a camping / gear list tomorrow night pending the final decision.
