I did the Mountaineer's Route car-to-car on Tuesday (6/27). The creek crossings are absolutely passable, but not without having to wade through calf to thigh deep water. The main crossing at the outlet of Lower Boy Scout is wide and deep! There's an alternate crossing up a little higher by the large boulder, but you're still gonna get wet.
Snow starts above Upper Boy Scout Lake. There are two traversing boot packs below the headwall of Iceberg Lake, I'd suggest taking the lower. I ended up on the upper in the dark, and it deposits you just below the seeps/waterfalls and will require some front pointing on the snow slope above. No big deal, but the lower is easier. Deep sun cups are a pain to walk in!
If you make your way up the snow slope from Iceberg to the Notch in the early AM, it's nice and firm and you'll get softer conditions for the descent. The final 400 feet to the summit after the Notch still has a steep snow field towards the top with ice and verglass below, but can be climbed sans crampons and ice axe if you class 3/4 the rock band to the right all the way up (and down).
