Notes on Trail Conditions
Trail conditions are updated when information is available, either through park staff or visitor reports. Updated information may be delayed or changed by varying weather and staff capabilities. When snow is mostly gone from the trails, we stop regular updates and only add significant changes to trail conditions or status.
