Ski and snowboard enthusiasts from around the world:

We have been proud to provide you with free access to snow reports, resort guides and more, and we are beyond grateful for your readership and contributions to our community over the years.

Unfortunately given the changing media landscape, Mountain News Corporation has experienced financial declines in recent years. With additional economic challenges from the COVID-19 pandemic now facing our business, it is not financially viable to continue operating.

Mountain News Corporation and our OnTheSnow and Skiinfo websites will be shutting down. We will explore the possibility of selling, partnering, or contributing assets to another media outlet if there is an opportunity to allow for a consistent or enhanced online experience. For inquiries about Mountain News Corporation, please email Feedback_OTS@mountainnews.com.

We want to thank our loyal employees for their tireless work over the years to bring great information to all of you. We take comfort knowing that our collective passion for the sport of skiing and snowboarding will certainly live on.

We’ll see you on the mountain.

Something is very wrong at Sun Valley this March. The lifts aren’t very reliable the last few weeks and they have stopped adding more snow despite the colder temperatures. A warm spell will turn the mountain to mush!

Skied Monday the 27th. Sunny day. No lift lines, like usual. Seattle ridge stayed in great shape. Frenchmen runs were getting scraped back to almost icy conditions. Top of Mayday still had some relatively deep untracked areas but as you descend it becomes full of large moguls.

Mountain News Corporation and our OnTheSnow and Skiinfo websites will be shutting down. We will explore the possibility of selling, partnering, or contributing assets to another media outlet if there is an opportunity to allow for a consistent or enhanced online experience. For inquiries about Mountain News Corporation, please email Feedback_OTS@mountainnews.com.

We want to thank our loyal employees for their tireless work over the years to bring great information to all of you. We take comfort knowing that our collective passion for the sport of skiing and snowboarding will certainly live on.

We’ll see you on the mountain.
