Hunters are the largest group of people who use Green Ridge, and DNR's plan calls it one of the most popular public hunting areas in Maryland. Maryland began licensing hunters in 1916. As printed in DNR's 2019 plan, licence sales peaked at about 180,000 in the early 1970s and later fell to about 135,000. The hunting camps came early. A 1920s board-and-batten cabin on Oldtown Road, surveyed in the 1970s, is one of many such vacation and hunting cabins once scattered through these mountains, and a nineteenth-century log farmhouse on Appel Road was by then lived in only in hunting season. In 1975 the owner of the Little Orleans store told the Cumberland News that his busiest week of the year was deer season. In the 1990–91 seasons hunters reported 1,360 deer taken in the forest, and DNR estimated a herd of about 3,590, or 35 to 45 deer per square mile. In October 2004 Maryland held its first black bear season in 51 years. Most of the forest is open to hunting and trapping in season; target shooting is allowed only at the forest's shooting range, which was paid for with hunting licence fees and is used by permit from headquarters.

The Potomac here was a border, with the canal and the Baltimore and Ohio Railroad running along it. In the winter of 1862, according to the Morgan County historical society, Brigadier General Frederick W. Lander held the river line with about 16,000 Union troops quartered at Camp Chase near Paw Paw; Lander died there of pneumonia on 2 March 1862. On 4 October 1862 Confederate troops under John Imboden attacked Company K of the 54th Pennsylvania at the mouth of the Little Cacapon, and their cavalry captured Company B, camped about 500 yards from the Paw Paw Tunnel. In June 1863 raiders under Lieutenant Colonel Elijah White cut the canal just below Lock 67 and between Locks 71 and 72. In the summer of 1864 raiders captured 14 canal boats near Lock 68, most of them loaded with coal, and set them on fire, with the pivot bridge over the lock. Union troops stationed at Little Orleans are said to have used Point Lookout and the nearby ridges to watch the canal, the railroad and the river crossings, and DNR gives that as the likely origin of the overlook's name. In Flintstone, Confederate troops looted the Wilson family's store, which still stood on Old Route 40 when it was surveyed. On 2 August 1864, at the forest's southwest edge, Confederate cavalry under Brigadier General John McCausland, retreating after burning Chambersburg, Pennsylvania, reached the river at Oldtown. Colonel Israel Stough held the crossing with part of the 153rd Ohio, a blockhouse and an iron-clad train. A Confederate gun put a shot through the train's boiler, and Stough, outnumbered, surrendered on condition that his men be paroled at once. In his report, General Kelley gave Confederate losses of 20 to 25 killed and 40 to 50 wounded, and Union losses of 2 killed and 3 wounded.
