From the notch, contour out toward Snowdome as shown on the overview topo. Lumpy space makes it challenging to follow a level path without losing any elevation. Don't get sucked into climbing too soon. Approach the summit as shown by the red line below.
Skiing off the summit is northwest facing at 39 degrees for 900' vertical. You can contour back the way you came, or continue farther down the fall line. As you go toward Allison Lake there are pillows, open areas, and a few cliff bands.
