On April 8, 1844, portions of land were taken from Hanover Township and Pequannock and Rockaway Township was incorporated as a township. 69 years later, on April 14, 1913, Denville Township was formed using a portion of Rockaway Township. Over the next 58 years after the separation, residents of both lake towns would take the sticks and pucks, put on their steel blades and enjoy the game of hockey on their own frozen lakes.
In 1971, Denville PAL Hockey was born followed by the formation of Rockaway Township Hockey, three years later, in 1974. During the next 48 years, a friendly, but deep seeded rivalry for superiority existed. Both local hockey programs would ultimately feed into the Morris Knolls Golden Eagles Ice Hockey program. However, the players grew up playing against one another as foes instead of allies.
Finally in 2022, after 109 years of division, the rivalry will end as the Denville Township and Rockaway Township hockey programs begin reunification with the birth of Eagles Ice Hockey.
