Boulder across the road at ~640m elevation, quickly followed by a large washout. This would be passable in a quad or dirt bike, but not a truck. Road up to that point was easily passable in a Subaru Forester, but somewhat degraded.

We took ebikes up past the washout to ~1000m elevation on the EC5000 (which does not end where shown on this site but actually continues up to the lake below Silver Peak at 1600m) where we hit snow. Snow was mostly continuous from that point on (skis off twice) but melting out rapidly.
