In late season, the Snow Dome can be accessed from the Timberline Trail and a climber's trail along the Elliot Glacier north lateral moraine.

Ski the Snow Dome and the lower Elliot along your line of ascent, or for a longer tour drop to the north at the base of the Snow Dome (circa 7800') to access the Langille Glacier, ski north to the Timberline Trail, and follow the trail to Cloud Cap and Tilly Jane. The Snow Dome descent presents an intermediate ski run with few hazards and snow conditions that you've already assessed.

You have two descent options to choose between: The Snow Dome or Elliot Glacier. You might dig a snow pit to assess conditions/stability for the steep drop into the Elliot Glacier. Enjoy views of the Elliot Headwall and Cathedral Ridge looming above you. Access the snow dome area at circa 7800' and either boot or skin to the top of the dome where it terminates at cliff bands, circa 9650'. Cross the glacier heading west below the small remnant icefall to climb the north lateral moraine. If all looks well, then a well-trod path usually traverses the moraine SW dropping gently to the Elliot Glacier. Assess the condition of the lower Elliot Glacier here to confirm that you can cross safely to the north lateral moraine.

From the cabin area ascend to the south lateral moraine of the Elliot Glacier circa 6870' in the vicinity of the Cooper Spur Shelter.

Skin or hike to the Tilly Jane cabin area from either the Cooper Spur snow park via the Polallie Trail, or the Tilly Jane snow park and the Tilly Jane Trail. Melting and shrinkage has affected both the Elliot Glacier and the Snow Dome, which now resembles more of a ramp than a dome. Just a few decades ago the Snow Dome stood out as a white dome crowning the divide between the Elliot and Coe Glaciers at an elevation between 7800' to 9700'.
