While thought of as the highest point in the area, its summit reaching approximately 1,340 feet (410 m) above sea level, the eastern summit known officially as Butter Hill is actually higher, with an elevation of 1,380 feet (420 m).
Name
During his initial voyage up the river, Henry Hudson and his crew named the mountain Klinkesberg, due to its wrinkled rock cliffs near the river.
Later, the early Dutchcolonists of the region referred to the mountain simply as "Boterberg" (Butter Hill, since the mountain looked like a lump of butter; the English translation was later the common name for the mountain). During the middle of the 19th century, writer Nathaniel Parker Willis, who had become a resident in the region, proposed the name Storm King:
The tallest mountain is ... looked upon as the most sure foreteller of a storm. When the white cloud-beard descends upon his breast in the morning ... there is sure to be a rain-storm before night. Standing aloft before other mountains in the chain, this sign is peculiar to him. He seems the monarch, and this seems his stately ordering of a change in the weather. Should not STORM-KING, then, be his proper title?
The section of New York State Route 218 that winds around the eastern slope of the mountain overlooking the River Hudson was originally named the Storm King Highway. That name is often used presently for the four-lane section of U.S. Route 9W to the west, with Route 218 referred to as the Old Storm King Highway.
After forest fires on the mountain during the dry summer of 1999, unexploded ordnance remaining from 19th century artillery tests and training at the nearby United States Military Academy was discovered in some areas close to the trails. As a result, hiking on the mountain was prohibited until October 2002, when authorities could be sure it had been removed safely.
On February 20, 2011, a NYPD helicopter rescued two Fourth Class "plebes" from the United States Military Academy nearby, who had stranded themselves 500 feet up on the southern cliff face while rappelling,[4] when a New York State Police chopper proved unable to complete the task.
Hiking
The mountain is a major part of Storm King State Park. With wide views of the river and areas surrounding, both Storm King and Butter Hill summits are popular with hikers. The orange-blazed unnamed connector trail, leading to the yellow-blazed Stillman Trail, most often accessed at a parking area on U.S. Route 9W, offers an immediate and steep climb up Butter Hill followed by a longer and more relaxing hike to the summit of Storm King.
Although attempted infrequently and not permitted by the park authorities, there are documented technical rock climbing routes above the river, as well as ice climbing, when conditions are favorable.
