Are you asking about the standard Whitney trail? Was there last weekend (6/23-24), and there's two patches of snow: (1) by cables, and (2) trail crest. Both are melting out quickly and have bomber boot packs. No need to bring any traction devices or axes.
I was up on the Mountaineers' Route this weekend (6/30). No snow on the approach to Iceberg Lake. Small amount of snow in the Chute and at the top of the Mountaineers', but it's easy (and advisable) to avoid. Crampons & ice axes not needed.
