The reservation is named after the Eagle Rock, a bare rock looking down from the mountain, which marks the boundary between the towns of Montclair and West Orange, New Jersey. The Lenape Trail passes through the reservation. There are many streams that flow throughout the reservation. The forests are home to abundant wildlife, including deer and bears.
After the September 11 terrorist attacks, residents of nearby communities gathered to view the aftermath of the attacks on the World Trade Center. Because of this, on October 20, 2002, Essex County Executive James W. Treffinger, along with many local residents and dignitaries, dedicated a section of the reservation, which overlooks the Manhattan skyline, to a memorial built in honor of those killed during the attacks. The names of all who perished at the World Trade Center or on the two planes that crashed into the twin towers are permanently inscribed in a marble memorial.
