I've found several reports for people climbing the Mountaineers Route for the past weekend. It sounds like a lot of people are climbing it on weekends. The past weekend was ideal weather. Click on the pictures for the enlarged size.

RC and Tammy climbing the Ebersbacher Ledges "E-Ledges" on Whitney's North Fork Trail (Mountaineers Route) 04-03-16
...the North facing sides had hard iced snow from 9000ft. The whole trail after 10k ft had snow
...Yes the snow starts at around 9k ft, none at E Ledges, then the rest of the trail is completely covered with snow
... The whole route passed Lower Boy Scout Lake is covered by snow/icy snow




Here's a picture taken from near Iceberg Lake, posted on instagram by ourmillionmiles.

Tam and @robfu starting their way up the chute to Whitney's summit. It took about three hours. It's crazy how this picture makes the chute look small. But it actually seems to last forever. And for what it's worth, I'd choose doing this route in the snow any day. (4-3-16)

RobFu reported they came down this route because the Final 400 "had a traffic jam".
