On average, there's about 18" of settled storm snow (up to 30" in leeward terrain) down to the 4/26 interface, which is typically a melt-freeze crust. The interface was dry facets on a due north slope at 13,000'. The snow surface was staying dry through most of the day around the compass, but this afternoon in the far Northern Ruby Range, we found the top inch or two had gotten moist or wet on all but due north, causing numerous small rollerballs. Triggered a couple of wind slabs, and noted a handful of natural wind slabs in the past 24 hours. Some slopes around Purple Mtn produced rollerballs on east and northeast aspects above treeline.

Northerly facing slopes were producing roller balls below some rocks and trees. A north-facing slope at 11,300ft still had a cold snow surface. While NE-E facing slopes had roller balls up to ~11,500ft in this area. NTL/BTL northerly facing slopes still have transitioning snow that could produce wet loose avalanches with warmer temps. The easterly facing bowl below Purple Ridge looked textured and like it was producing roller balls. ZG, will have better alpine obs. Hand shears on a north-facing slope at 11,300ft were resistant and had a rough bed surface near the old snow interface. . Roller balls

Prior to ski cutting numerous slabs along the top of Schuylkill Ridge, we observed minimal signs of instability on our uproute. We targeted a few steep, windloaded slopes and observed minor cracking, both a few inches thick and up to 18" deep on the 4/26 crust, less than 2' long. We also noticed a couple of small collapses while breaking trail.

In the valley floor near Pittsburg, around 6" of storm snow in the morning cooked down to around 3" by the afternoon, fully transitioning to wet snow by the afternoon. Up to about 10,500', the partially transitioned new snow covered a still-wet and unsupportive spring snowpack. Above around 11,500', the crusts buried below the storm snow became fully supportive to boots, and the travel conditions remained dry and very good even into mid-afternoon. Near 12,000 feet, the dense storm snow was around 14" deep, and we found minor drifts up to about 16" deep. Throughout the elevation bands, we found no cracking or collapsing. The only place where the new snow was not well-bonded throughout was below some cliff bands, where graupel pooled midway through the storm snow. Above treeline, even steep, due south-facing snow stayed dry with the cloud cover. Likely, this effect was only along the spine of the Ruby Range.

The storm interface is a melt-freeze crust everywhere except for due north above ~12,800', which is small-grained facets (where the snow stayed dry last week). Northeast aspects ATL have a crust/facet/crust sandwich: the upper crust is about 1cm thick and strong enough that it wasn't collapsing under the current load, and none of the avalanches broke deeper than the storm interface. . Shooting cracks above treeline on wind-loaded and wind-sheltered slopes.

Storm totals around 6 inches at 1 pm near treeline. There is lower-density snow near the crust interface with denser snow above, including a graupel layer at the surface. I didn't encounter any significant wind loading in this terrain, but leeward features were top-heavy and produced short cracks. Today's easy sluffing on steep features could produce shallow soft slabs with more snowfall, or wind slab issues on well-drifted features at higher elevations. On features steeper than 40 degrees, it was easy to produce loose avalanches in the new snow. I hunted for drifted features in this near treeline zone and only produced short running cracks.

This area picked up about 6 to 8 inches of storm snow on Wednesday and Wednesday night. Warm temperatures and ample sunshine quickly impacted this snow on Thursday, and cooked it down to about 3 inches in depth, leading to a minor cycle of small wet avalanche activity, not exceeding D1 in size. A cold night on Thursday solidly froze the snow surface, and Thursday morning saw a stout 1-inch thick crust preserving an inch or two colder snow underneath. Snow picked up again on Friday with storm totals of about 5 to 6 inches by Friday afternoon. The last round of snow fell onto cold, frozen surfaces and will sluff off easily in steep terrain.

Aspen

Published: Apr 14th, 2026

Below treeline there was only 1 or 2 inches of new snow, falling on bare ground on many slopes or somewhat discontinuous snow on north-facing slopes. Above about 11,000 feet, there was around 4 inches of new snow with wind-drifted spots around 6 inches deep. The old snow surface crusts were still mostly soft and moist, not entirely refrozen, which made for pleasant ski conditions. Slopes facing west southeast through south to west, even above treeline, are really showing the historically dry and hot winter and are mostly bare ground. The only slopes with continuous snow coverage are northwest through north to some east above 10,500 feet.

ATL: We found good stability and dry snow surfaces on northeast aspects, boot top ski pen. There were a few small stiff drifts that we steered away from, given the high-consequence terrain. East aspects were becoming moist and sluffing easier. NTL: East and SE aspects were wet and producing rollerballs, pinwheels, and wet loose. NE aspects were dry to moist. BTL: Large rollerballs and pinwheels, with wet loose avalanches involving all the April Fools snow (about 12" to 16"). . Large rollerballs and pinwheels developed by 10:30 a.m, along with wet loose activity.

We ascended through westerly facing forested terrain to the summit. No notable observations on the ascent other than signs of wind drifting overnight with tracks from Friday being partially blown in 3rd Bowl. We avoided the most drifted terrain and didn't encounter signs of instability around 12,000 feet. I briefly stomped on heavily drifted southeast terrain without result. There were numerous tracks on steep northerly terrain in 3rd, 4th, 5th, and 6th bowls without any significant sluffing or avalanches. Southerly terrain near 12,000 feet remained cool just before noon with little evidence to support wet loose avalanche concerns.

Storm totals since Tuesday slightly exceed two feet in this area at treeline. Warm temperatures and sunshine on Thursday formed a soft 1-2cm crust on southerly aspects, with a few inches of snow above from Thursday night. Solar aspects became slightly moist around midday. We crossed a handful of recently drifted features without result. Several ECT's did not produce propagating results. ECTN's in this week's storm snow broke only a shovel width on storm density changes, but did not appear problematic. In each spot I looked, this week's storm snow was well-bonded to the crust below. Minor cracking was found a few inches deep in last night's wind-drifted snow. No significant signs of instability underfoot. Minor cracking of a few feet in drifted snow from Thursday night.

3 to 4 inches of new snow from last night. The current wind slab problem appeared to be mostly confined to this new snow in the area. Minor sluffing in steep terrain. Easterly facing slopes at ~11,600 or 11,700 were starting to get cooked. Low-angle slopes up to our high point had a breakable crust under the new snow that would have made for poor ski quality. Snow quality on northerly facing slopes began to decrease below about 10,300ft. . We found good stability while avoiding some of the most obvious wind-loaded terrain.

You could have gotten confused by yesterday's snowfall with fresh mixed concrete as it was so heavy and sloppy. The 24 hour new snow total was 12" new with water content of 1.41 inches, almost 12% water while the average snow density in winter up to this data is 6.67%. The snowpack is up to 22". Currently overcast with very light snow and light westerly wind but occasionally gusting and the overnight temperature range a high of 31 and low the current 29 after a high yesterday of 37. The high irony is that yesterday set a record for the most snow on any April 01. But this winter no longer has the lowest snowpack on this date or the least amount of snowfall for any winter to this date.

Coverage was thin below ~10,000 ft, where 8-10" of new snow was on bare ground or a thin snowpack comprised of mostly large, wet grains. As we gained elevation, we observed 20-25" of new snow that had 10" of more dense, moist snow on top of snow from earlier in the storm that was less dense. The storm interface in BTL elevations below ~10,500 ft was a thin, melt-freeze crust over moist-to-wet grains to the ground. Near 11,300 ft, we observed a refrozen interface that was ~20cm thick. . The top half of the storm snow was upside-down and produced consistent minor collapses while breaking trail, about a foot deep. We observed a couple of larger collapses where the storm interface (a melt-freeze crust) collapsed into wet snow below it, about 2 feet deep.
