I did a solo summit back in July 2017 all in one day.
Snowfall last year was massive so in July, the switchbacks were inaccessible and the only way up/down was the chute.
Never once felt unsafe and did end up running into her hikers as well, even in the middle of the night. At certain points, I coudln't find the trail due to the snow but having GPS helps.
In reasonable shape, have some backpacking experience, and didn't have any issues with the altitude (I've gone as high as about 18k in the past).
