Well, cripes, I thought the Highline Trail would be clear already, but today is the official opening. Here is the core part of the official press release . . .
The popular Highline Trail at Logan Pass is anticipated to be open by Friday, possibly earlier. Hikers are encouraged to plan ahead and be prepared. Hikers may encounter rocks and mud on trails, eroded trail tread, and some snowfields on higher elevation trails across the park.
Due to recent mud and rock slides along the Highline Trail, both west and east-side park trail crews have been working to allow for public access on the trail from Logan Pass to Haystack Butte. On July 17 a rain event triggered numerous mud and rock slides in the area and deposited lots of rock and mud debris on the trail. Much of the tread, flat surfaces or step-like features built by trail crew, were washed out. In several areas of the trail, bedrock is exposed and hikers are encouraged to use caution. Often the bedrock is angled downhill, wet, and potentially slick.The use of hiking poles is encouraged in this area.
Visitors planning to hike on trails in the higher elevations of the park are encouraged to have appropriate footwear for snow travel, specifically lug-sole boots, and self-arrest tools such as ice axe and crampons, as well as the knowledge and skills to utilize the tools. It is recommended to have layers of clothing available, including a rain jacket, for changing weather conditions throughout the park. Caution should be used near rivers and streams, as water may be extremely cold, and running swift and high. All hikers are encouraged to turn around if conditions exceed what is comfortable or beyond personal experience and limitations.
