The Loft route is melting rapidly, but as of now it's still going to be almost
100% snow from the Chasm Lake cabin to the escape ledges. Above that
basically no snow, except that there is still a good patch on the lower
Homestretch before you meet up with the Keyhole Route. Don't know if
that will be melted out by next week or not, but if not it can be tricky there
as it is somewhat steep with a bad run-out were one to take a fall there.
Personally, I would carry crampons & ax for this route unless I had
confirmation that the snow on the lower Homestretch was gone or
avoidable. On the upper Homestretch, where the Loft/Clarks Arrow route
meets the Keyhole route, there is snow but it is easily avoidable.
