Blaine County issued the following announcement on March 29.
Trail Creek is still closed for the season. Although most of the snow in the valley has melted, Trail Creek Summit still has snow and mud at higher elevations. The Blaine County Road and Bridge department asks that everyone stays off Trail Creek Summit until they are able to open the road later this spring. We will post any updates on social media and the Blaine County website.
