Duane,
We hiked 13 miles on a day hike. The snow was very light. The road up from Mammoth Mountain Inn to the pass is maintained for cross country skiing, so the early hiking was on packed snow. Once you cross the pass, the road descends with southern exposure, so it was clear of snow, although frozen runoff from the afternoon before made for tricky ice patches across the road. From Agnew Campground the snow was about 18", but the combination of few travelers, the underlying trail, some southern exposure, etc made it reasonable in boots. We went out to the Shadow lake trail junction and back.
