There are about 400 acres of patented mining claims relating to this ore body. The Park Service responded with environmental studies in the early 1970s in order to anticipate the effect that possible mineral development might have on the park. Though there are minor indications of human use, the area remains quite pristine. In 1980, Congress designated the lands surrounding the Brady Glacier claims as wilderness. Researchers in the 1970s found that the abundant black bears, wolves and goats, for instance, showed little knowledge of people.
Plant communities remain almost untouched.
With the possible exception of lingcod and rockfish, which may have been fished heavily at times, the marine environment is probably in relatively unaltered condition. Torch Bay and especially Graves Harbor are important seasonal anchorages for the commercial fishing fleet. At other times of year on the coast, and nearly always inland, the opportunities for solitude are very great. Though not used heavily for recreation, the area is ideal for sea kayaking, wildlife viewing and hiking on the beaches and alpine ridges, although the weather can be severe at times. Some winter ski trekking occurs on the Brady Glacier.
