OAP still has some snow on the upper end of the trail. NAP has a small passable snow bank at the last switchback.
I just returned from Rock Creek and the Upper Miter Basin near Crabtree Pass (July 3rd - 6th). The mosquitoes at Rock Creek are terrible, as is the entry into Miter Basin (swarms on the attack!).
Sky Blue Lake had a few bugs, but not many. Upper Lakes near Crabtree Pass had no bugs.
I forgot how nasty the bugs are in early summer in the Sierra. I usually wait to hike deep into the Sierra from late August to October to avoid the swarms of blood-thirsty mosquitoes.
Hope this helps!
