With Friday's forecast of mostly sunny and very cold temperatures near 0 °F in the mountains, sunny south-facing slopes seemed to be the best bet to find good skiing while not freezing off any important body parts. Dave Coleman and I headed to Paradise, planning to take a look at SW-facing lines dropping onto the Nisqually Glacier from the lower Muir Snowfield, hoping to find deep light powder without significant wind-affect or wind-loading. Telemetry showed about 37" of new snow at Paradise over the previous 3+ days, all of it falling in cold temps below 20 °F, with initially strong west winds decreasing throughout the storm cycle and staying fairly light over the previous day.

We reached Longmire just minutes before the gate opened at 9:45am, having driven on snow-packed highway all the way from South Hill onward, and arrived at Paradise to find it shockingly almost-warm with temps a balmy 16 °F in the parking lot, a huge jump from the 1 °F seen on the 7am telemetry. We set off at 10:45am, breaking trail through 1-2 feet of unconsolidated new snow. We followed a few sections of older snow-filled skin track up to about 5900 ft, but above that there was no sign of previous travelers. The snow surface near Alta Vista and Glacier Vista became a wind-affected patchwork of deep powder and breakable wind crust, with some areas of supportive crust and occasional firm sastrugi 6-12" high.
We put in a cautious skin track up the right edge of Panorama Face, seeing the remains of two small, recent, natural soft slabs on the uppermost left side of the face. We exited right onto the safety of the SW ridge of Panorama Point at the usual spot through the trees, and continued up along the wind-hammered snow of the ridge. Unexpected clouds had been building in the valleys below, chasing us up the slope and bringing occasional flurries glinting in the sunshine. Winds remained under 5-10 mph above Pan Point, keeping things comfortable despite temps which were close to 0 °F by now.
We crossed Pebble Creek near the summer trail (7200 ft) and within another 100 ft, the clouds had engulfed us in near-whiteout. No point in continuing farther up into the alpine in such conditions. We ripped the skins and decided to ski the Pebble Creek drainage down to the Nisqually Glacier, hoping to find smooth light powder in the often wind-protected basin of the glacier. The drainage was mostly windslab and breakable crust, with a few areas of decent powder as we neared the Nisqually moraine and dropped onto the glacier.
A few turns in powder onto the Nisqually Glacier.
The glacier itself had some nice deep powder, some nice shallow powder atop smooth crust, and some not-so-nice breakable windcrust. We skied down to 5400 ft, skirting the edge of a large natural avalanche deposit which had released on a west aspect near 5800 ft at least a day earlier. The snow conditions worsened and the weather did too, quickly becoming a full-blown snowstorm.

Back on with the skins and back to breaking trail, up the Nisqually Glacier and back up to Glacier Vista, still in total solitude having seen no one else since we left Paradise. We traversed across into Edith Creek Basin on more breakable windcrust, then across into the next basin east, eventually finding the long-sought smooth deep light untracked powder. We enjoyed a sweet but short run down to 4th Crossing, then headed up an existing skin track for a quick lap on the west side of Mazama Ridge in the ongoing snowstorm. About 1-2" of new cold-smoke snow had already fallen in the skin track since the previous skiers had used it, and the run back down was outstanding in more deep light untracked powder. By now it was after 4pm, so it was time to call it a day and skin back up to Paradise.
A disappointing day perhaps, with the weather forecast turning out to be essentially 100% wrong (snowing with 1-2" new != mostly sunny), and snow conditions on the Nisqually being much more wind-affected than expected based on telemetry. But still a good day just to be out enjoying the renewed vigor of winter in the Cascades, with a couple modest runs of deep blower powder thrown in for good measure.

Plumes of snow blowing off the summit of Rainier, from the viewpoint on SR 161.
We reached Longmire just minutes before the gate opened at 9:45am, having driven on snow-packed highway all the way from South Hill onward, and arrived at Paradise to find it shockingly almost-warm with temps a balmy 16 °F in the parking lot, a huge jump from the 1 °F seen on the 7am telemetry. We set off at 10:45am, breaking trail through 1-2 feet of unconsolidated new snow. We followed a few sections of older snow-filled skin track up to about 5900 ft, but above that there was no sign of previous travelers. The snow surface near Alta Vista and Glacier Vista became a wind-affected patchwork of deep powder and breakable wind crust, with some areas of supportive crust and occasional firm sastrugi 6-12" high.
We put in a cautious skin track up the right edge of Panorama Face, seeing the remains of two small, recent, natural soft slabs on the uppermost left side of the face. We exited right onto the safety of the SW ridge of Panorama Point at the usual spot through the trees, and continued up along the wind-hammered snow of the ridge. Unexpected clouds had been building in the valleys below, chasing us up the slope and bringing occasional flurries glinting in the sunshine. Winds remained under 5-10 mph above Pan Point, keeping things comfortable despite temps which were close to 0 °F by now.
We crossed Pebble Creek near the summer trail (7200 ft) and within another 100 ft, the clouds had engulfed us in near-whiteout. No point in continuing farther up into the alpine in such conditions. We ripped the skins and decided to ski the Pebble Creek drainage down to the Nisqually Glacier, hoping to find smooth light powder in the often wind-protected basin of the glacier. The drainage was mostly windslab and breakable crust, with a few areas of decent powder as we neared the Nisqually moraine and dropped onto the glacier.
A few turns in powder onto the Nisqually Glacier.
The glacier itself had some nice deep powder, some nice shallow powder atop smooth crust, and some not-so-nice breakable windcrust. We skied down to 5400 ft, skirting the edge of a large natural avalanche deposit which had released on a west aspect near 5800 ft at least a day earlier. The snow conditions worsened and the weather did too, quickly becoming a full-blown snowstorm.

Back on with the skins and back to breaking trail, up the Nisqually Glacier and back up to Glacier Vista, still in total solitude having seen no one else since we left Paradise. We traversed across into Edith Creek Basin on more breakable windcrust, then across into the next basin east, eventually finding the long-sought smooth deep light untracked powder. We enjoyed a sweet but short run down to 4th Crossing, then headed up an existing skin track for a quick lap on the west side of Mazama Ridge in the ongoing snowstorm. About 1-2" of new cold-smoke snow had already fallen in the skin track since the previous skiers had used it, and the run back down was outstanding in more deep light untracked powder. By now it was after 4pm, so it was time to call it a day and skin back up to Paradise.
A disappointing day perhaps, with the weather forecast turning out to be essentially 100% wrong (snowing with 1-2" new != mostly sunny), and snow conditions on the Nisqually being much more wind-affected than expected based on telemetry. But still a good day just to be out enjoying the renewed vigor of winter in the Cascades, with a couple modest runs of deep blower powder thrown in for good measure.

great pix as always! way to get out there amar
I could see your squiggles on Mazama when I made a break for the parking lot from above pan point. I wish I would have gone that way from the get go!
thanks again for another nice report
We were 150' short of Foss peak when when the real snow began.With reduced vis and windpack left above us we turned around also. Our consolation prize was the powder ski on exit . Sluff mangement on steeper pitches was our only " problem ?" Not a lot of skiers in some of the best powder of the year. I noticed some ski tracks at exit of Nisqually at the bridge. Hard to imagine enough glide out in the deep snow on lower glacier.

Great pics, you always have some of the best!!!!! I ended up golfing in the rain in LA that day, so like experienced disappointing conditions :>).
Great report, Amar.
Thanks.
Thanks.
