Just follow your map where the trail is indicated - if you can read topo, it's pretty clear, even though there won't be any trail visible. (Or, take a GPS unit.) However, there should also be plenty of boot tracks that you can follow as well - just be aware not to follow any that appear to peter off.
There are two sections where the winter route can leave the standard trail: - Above Outpost & the waterfall, you can follow the fork up the LP creek drainage that skirts Consultation rather than climb the (snow covered) rocks (both routes still end up @ Trail camp) - the Chute vs the 99 switchbacks
Here's what both the fork and the Chute looked like last year (2016) during the first week of May:
Upon your return down the drainage past TC, pay very close attention to ensure making the left turn over the (snow covered) rocks to descend towards Mirror & Outpost. Last year (when I took these shots), I ran into a group @ Outpost that missed the turn and came down the waterfall. They were pumped from adrenaline, but otherwise ok.
I'm going up today, so I'll post some photos later this week.
