A section of H-13 in Alger County originally continued north to Miners Castle, but the roadway designation was truncated in the first decade of the 21st century.

[4][7][8] The road meanders from there northeasterly through rural Delta County forests, passing to the west of Dana and Skeels lakes and crossing several small streams.

The road continues northeasterly and then meanders back and forth along the Alger–Schoolcraft county line in an area dotted with several lakes.

Once the road crosses back into Alger County completely, it provides access to Wagner Falls State Park and passes Hanley Field, a private airport south of Wetmore.

At that junction, the FFH-13 designation ends and H-13 continues north as a gravel surface along Connors Road through Munising Township.

[13] During World War II, the gravel surface was downgraded to earth along Miners Castle Road.
