Based on what I found 2 weeks ago on Dickey Peak, I'd not go anywhere near the Lost Rivers after a recent sizeable snowfall. The snowpack then was the worst imaginable, with a foot or two of cohesionless facets capped by crusts of variable thickness. It was textbook sugar snow that would not be able to withstand even a modest load of new snow.
I have no idea how much new snow the range has received in the past week.
