In my experience rangers on the phone almost never know anything about actual snow conditions and if they do know anything they vastly overstate the amount of snow. Things have melted fairly fast over the last month, the Desolation does hold snow later than most places around Tahoe but otherwise the TRT is getting pretty clear, I have friends who run it daily.
I hiked Cloud’s Rest back on May 5th and approaching from the South didn’t see any snow all of the way to the summit (10,000). Back then there was a foot of snow on the north slope.
I hiked Onion Valley to Glen Pass on May 27 and saw minimal snow. Kearsarge pass (11,700 and East / West oriented) was totally clear. Glen pass (12,000 and North / South oriented) was totally clear on the south side but 2 feet deep on the North side.
When I drove home over Tioga pass road last weekend Tuolumne was all melted out at road level, with only northern aspects of the taller peaks (11,000+) Â in the area still holding snow. By the time I passed the Ten Lakes trailhead I hadn’t seen any snow for quite some time.
There may be small patches of lingering snow but I’d be very, very surprised if you saw any significant snow in the Ten Lakes / May Lake area. 4 feet of snow at Ten Lakes pass is ludicrous.
