Knowing snow levels would be extremely helpful so to start, here's an update from a 3/19 ascent.
Per the climbing report (now stating 5' base at the lot), there's snow for the entirety of the route, no issues riding right on out.
No major obstacles that I could see below the 4,800' marker either and mostly snow above with just one real stretch of rock on the climb up to work through. Lots of cornices, snow fractures and debris from recent slides around however.
The upper route was pretty icy even in the mid morning sun though it softened up completely by about 2. Few people went for the summit and most that did took some variation across the Swift rather than cutting over to Monitor Ridge though a few came down that way.
Not sure how long the April paid permits have been required but it was that way last year (500 people / day from 4/1 - 5/15 with a Sno-park pass still required in April, Recreation Pass in May as well.)
