Small slabs on North Maggie's

We planned to ski the North glades on North and South Maggies today to find soft snow and avoid the forecasted wind slab issues above treeline. We descended South Maggie's at 10.45am to Eagle Lake through the North glades. We did not observe any signs of instability throughout our ascent and descent of South Maggie's, and hence decided to ski North Maggie's too. We ascended North Maggie's from Eagle Lake via the saddle that connects Maggie's Peaks, which notably wraps around the back and did not allow us to observe the North face that we were planning to ski off North Maggie's. We descended North Maggie's at 12.20pm through the skiers' right chute from the summit and continued fall line on the North slope. We noticed a substantial amount of slough in steeper pitches and some of this was coming loose in very small slabs, especially as we descended in elevation. We decided to move skiers' left around 7800ft to aim to exit at the Eagle Creek drainage, and at this point had to traverse a steep slope. The first skier in our party cut the slope at a convex roll while traversing skier's left and released a cohesive slab which ran ~10ft before stopping at the trees. The crown measured 4-6in in depth, and the slab did not appear to fail on a hoar or graupel layer, but a hard and shiny crust. We think this might have been a rain crust from the wet AR last weekend with high snow levels that the new storm snow or wind-transported snow failed to bond to.
