Wonderland Trail

The dominant condition here is snow coverage at elevation. With 31 inches still on the ground, large sections of the Wonderland Trail above ~4,500 ft will be snow-covered, and north-facing slopes won't see meaningful softening until late morning at the earliest. Nights are dropping to 24–28°F through the weekend, which means the snowpack refreezes hard overnight — expect icy crust on any shaded aspect in the early morning hours. Bring microspikes or crampons and poles; the trail tread will be buried and steep traverses (think the Carbon River to Spray Park section, or Panhandle Gap at 6,800 ft) will be firm névé until the sun hits them. The Long Lake SNOTEL at 840 ft is showing 61 inches and a falling trend, which is settlement and melt at lower elevations — that's fine for trail travel down low, but it tells you the higher-elevation snowpack is still substantial.

Weather is legitimately good this weekend. Highs in the mid-to-upper 30s with mostly sunny skies Friday through Sunday, light westerly winds under 18 mph, and essentially no precipitation until Sunday night when there's a 43% chance of snow. That Sunday night system is worth watching — if you're still out Monday morning you may wake up to fresh snow on top of icy crust, which complicates travel on steep terrain. Plan to be at a lower-elevation camp or heading out by Sunday afternoon. The warm daytime temperatures combined with overnight refreeze will drive a classic melt-freeze cycle: travel is fastest and safest on the crust in the early morning, and slopes will be soft and punchy by early afternoon.

Stream crossings are not a concern right now. All five gauges in the region are running at or below median flows, with a stable-to-falling trend. No snowmelt pulse is showing up yet — the cold overnight temps are suppressing runoff. That said, watch the crossing on the Carbon River drainage if your route takes you through the northwest quadrant; if Sunday's temperatures spike or the Sunday night precip comes in as rain at lower elevations, Monday afternoon flows could tick up. For your dates, crossings should be boot-top at worst.

No active fires within 50 miles and no smoke impacts. Daylight is exceptional — 15+ hours with sunset at 8:44 PM — so you have full flexibility on your daily schedule. Start moving by 7–8 AM to catch the firm morning snow before it softens, summit or cross high passes before 1 PM, and use the long evening light for camp chores. The biggest logistical note: navigation above treeline will require map and compass or GPS competence since trail markers are buried. Know your intended camps and the terrain around them before you leave the trailhead.
