I attempted to hike Ten Lakes this morning. I was surprised to see the parking lot on the other side of the trailhead closed, and there were no cars in the Ten Lakes parking lot. This is unhead of in July.
Sadly, I got 1.05 miles onto the trail and began encountering snow... lots of it. There were footprints of people who have traversed the snow banks, but then there were large sections of basically "lake like" conditions. I wasn't interested in wading to my thighs in water so I turned around. There was no way for me to find the trail, and I've hiked this 50 times in my life. You say you're going in a day or so, all I can say is, unless you an experienced snowshoer or know how to nagivate in heavy snow conditions, I wouldn't attept it at all. I didn't get anywhere close to where the real elevation gain starts, before the lakes begin. I would imagine that would be loaded with snow. If you're comfy with snow conditions and experienced, go for it. If not, I personally think it's way too dangerous.
I then tried McGee Creek hike on 395, south of Mammoth. That was fine for the first 2 miles, then stream crossings that were raging and then the bridge was basically washed out at 3.2 miles.
So a frustrating day of attempted hiking.
