Warm day for Winter, 40's and partly with light wind and gusts at the summits. Embarked solo from the AMR lot around 6:30 am, needed headlamps for an hour or so. Followed Lake Road until I veered off to the West River trail. Needed to switch to snowshoes right away (and for the rest of the day) as the snow was wet and hadn't been packed down in a while. Followed the WR trail to Wedge Brook trail, steeply ascending to the junction between the WJ's. Decided to climb LW first, then back to the junction and up to UW next, with MW on the way. Steep sections with tricky scrambles all the way, views at each summit before some clouds/haze rolled through. Ran into a handful of hiking groups so the return trip back the same way had more packed down trail. Overall great, but challenging hike with breaking in a lot of snow. Returned to the AMR lot around 4 pm. 4,725 ft elevation gain over 11.5 miles in 9.5 hours.
