Was on the main trail last week. We were clued in by descending hikers about how to avoid the snow field.
There is a bypass/use trail worked in just before you hit the snow. It's not that obvious but you can see it & there are cairns marking the way up. It's fairly steep with tight little switchbacks but it's short & intersects with the main trail above the snow.
But when coming off the summit make sure you look for it right away to the left or you will end up off trail in the snow like we did.
