Map Legend

[Danarch]

I’ve been looking around on the map and found the trail heading, but have a few questions. I am trying to figure out what the rectangle with the numbers are? I select them and nothing happens. I assume the black and white lines are the trails. Circled in red. Is there a method that list the difficulty of the trails?

The numbers in the rectangle are National Forest Roads, they are numbered and on the NFR maps.
