Quick hit. North lake leanto?

Its on my map for brwf... But no trail seems to lead to it... Is this a boat in lean to?



Isn't north lake heavily visited? Thus the lean to is hard to get?



I ask because its on the map... And it and sand lake falls are the only ones we have left in the brwf..



On that note is bear creek the best route( though longest) to sand lake in the spring.
