There was a lot of packed icy snow on the trail approaching Round Valley from the ranger station BEFORE the last storm. I'd worry about traction now if you're not carrying poles and/or instep crampons. I hope to be up there this weekend with snowshoes, and hope for enough white stuff to use them somewhere, like at the meadow by Round Vy.
My new Grivel Spider instep crampons worked fine on packed snow/ice. Real important if you're coming out at sunset or later and that easy crunchy surface has frozen into a slick ice sheet even though the air is not that cold yet. Fooled me earlier this year just before the concrete walk up to the tram. Bango!
Best, Todd in CC.
