This stretch of MCU caches are hidden along the publicly-accessible snowmobile trails maintained by the Perkins Ridge Sno-Travelers. These trails are open to hiking, snowmobiling, snowshoeing, skiing, horseback riding, and dog sledding. No knowledge of the MCU is required for these caches; they are along the lines of the Alien Invasion caches.
Mike Peterson first appears in the pilot episode of Agents of SHIELD as an average citizen experimented upon by Centipede after an accident leaves him jobless. Portrayed by J. August Richards, he later becomes the MCU version of Deathlok - a cyborg superhero.
