The peak was named in 1898 by Albert Hale Sylvester , a pioneer surveyor , explorer , topographer , and forest supervisor in the Cascades who named thousands of natural features . The first ascent of the summit was made July 26 , 1904 , by Sledge Tatum and George E. Louden , Jr. , two members of the Boundary Survey group led by Edward C. Barnard . Remmel Mountain was once topped by a gable roof single-room 14 ' by 14 ' fire lookout that was built by the Forest Service in the 1930s . The lookout was subject to heavy lightning strikes that forced its closure , and by 1969 was reported destroyed . Had it been still operating in 2001 , that fire lookout would have been in a position to locate the nearby Thirtymile Fire which killed four firefighters in Chewuch Canyon . The North Cascades features some of the most rugged topography in the Cascade Range with craggy peaks , granite spires , ridges , and deep glacial valleys . Geological events occurring many years ago created the diverse topography and drastic elevation changes over the Cascade Range leading to the various climate differences
