This blog post summarizes Killington Resort’s decision to close the Superstar Six lift and Superstar Trail after rainfall and overnight precipitation revealed snowpack instability.
It explains how a combination of near-record snowmaking totals and base depths exceeding 30 feet—paired with heavy, water-saturated snow and warming temperatures—led to structural concerns on the mountain.
It also covers the safety measures underway, the forecasted conditions that could speed snowmelt, and what this means for spring skiing at Killington.
What happened: Snowpack instability and closures
Recent rainfall (about 1–2 inches since early Tuesday) layered on top of near-record snowmaking totals created conditions conducive to instability on steep terrain.
Grooming crews detected movement in the snowpack and observed an 8–10‑foot‑deep crevasse on the Superstar Glacier, a clear indicator that the slope was shifting.
In response, Killington Resort closed the Superstar Six lift and the Superstar Trail to protect guests and preserve fragile snow cover.
The presence of a base depth greater than 30 feet means that even small increases in load or water content can destabilize larger layers beneath the surface.
The ongoing movement noted by grooming teams underscores the risk of sudden changes in slope integrity.
Ski Patrol is actively monitoring hazards, marking areas of concern, and identifying places where walking may be necessary due to thinning coverage.
Several trails, including Double Dipper, Needle’s Eye, and Highline, remain ungroomed as a strategic measure to manage spring conditions and protect the long-term snowpack.
Operational response and safety measures
To minimize risk while maintaining safety for guests and staff, Ski Patrol teams are intensifying hazard marking and using clear signage to direct movement on the mountain.
Grooming operations have been adjusted to avoid stressing weakened layers, and staff are prepared to guide visitors on safer routes when necessary.
- Superstar Six lift and Superstar Trail closures remain in effect while investigators monitor stability.
- Several trails (Double Dipper, Needle’s Eye, Highline) stay ungroomed as part of a risk-management strategy.
- Ski Patrol continues 24/7 hazard assessment, including marking zones where walking may be required.
- Grooming crew adjustments prioritize protecting the snowpack and avoiding unnecessary movement of saturated snow.
Forecast, spring skiing, and guest advisories
Forecasts indicate a wintry mix with likely freezing rain on Thursday, followed by partly sunny, warmer conditions on Friday with highs near 61°F.
This pattern will accelerate snowmelt and could alter on-mountain conditions rapidly.
Guests are urged to stay informed through Killington.com for real-time updates.
What visitors should know and how to plan
Knowing what to expect can help you plan a safer, more enjoyable visit during this period of variable spring conditions.
Consider the following actions:
- Check Killington.com for the latest closure and lift status before you head to the mountain.
- Be prepared for ungroomed and thinning coverage on some routes, including known hazard zones around the Superstar area.
- Walk only where directed by Ski Patrol and stay on marked trails to minimize personal risk.
- Dress in layers and consider traction aids if you anticipate icy patches or wet, heavy snow.
- Monitor weather updates and be ready for rapid changes as temperatures rise and melt accelerates.
