Are the suggested routes marked or maintained?

Summer routes are not marked. In winter, suggested routes are intermittently marked with blue diamonds, except in Wilderness Areas where tree blazes are used. From one trail marker, the next is usually not visible, making route finding an important skill for a successful trip. Winter routes are not maintained, so don’t anticipate a tracked or groomed trail. Even short trips with minimal elevation changes can become very challenging in whiteout conditions or if you have to break trail. Map and compass skills are essential.
