Pack the snowshoes away.
I've hiked Moose by this trail six or seven times over the last twenty some years on this weekend (the Cdn. May long weekend, always a week before Memorial).
The only spine you're likely to experience are remnants up on top as you skirt around the south side of Blue, then up through the final chunk of trail to treeline; usually the remnants are hard and no big deal.
Have fun.
