The way into the Emigrant Bowl (known as West Side by the locals) now that the Covered Wagon lift has closed.

FATMAP difficulty grade
The closure of the Covered Wagon lifts has made this approach slightly longer but it is still well worth the effort to reach these lines.
The approach can be done on foot or skins and which option you choose will likely depend on what kit you have, and how deep the snow looks.
If you don't have skins then a bit of clever micro route finding will minimise your uphill.
