History
Historically, the Kalmiopsis Wilderness was a mining district. Gold was discovered about 1850, causing a gold rush into the area. A number of mining towns were built and more than a dozen hard rock mines were started. Many people lived there up into the mid-1940s. In 1962, many of the homes and stores were still habitable and all the mining equipment and buildings were still in place.
The wilderness area was established in 1964. In 2002, lightning started the
Biscuit Fire that burned much of the area and damaged many of the hiking trails.
Some of the trails destroyed in the fire re-opened in 2015.

Topography
Elevations in Kalmiopsis Wilderness range from , at Pearsoll Peak. The area is characterized by deep, rough canyons, sharp rock ridges, and clear, rushing mountain streams and rivers. The wilderness includes the headwater basins of the Chetco, North Fork Smith Rivers, as well as part of the Illinois River

Geology
The Kalmiopsis Wilderness is part of the Klamath Mountain geologic province of northwestern California and southwestern Oregon. The eastern half is part of the Josephine "ultramafic" sheet, meaning it has a very high iron

content. The western half of the Wilderness is underlain by the sedimentary rocks of the Dothan formation and by the igneous intrusive rocks of the Big Craggies. Most of the rocks in this province were formerly parts of the oceanic crust, and include serpentine, submarine volcanic flow rocks, intrusive granite-like rocks, and sedimentary rocks such as shale
Shale is a fine-grained, clastic sedimentary rock formed from mud that is a mix of flakes of Clay mineral, clay minerals (hydrous aluminium phyllosilicates, e.g., Kaolinite, kaolin, aluminium, Al2Silicon, Si2Oxygen, O5(hydroxide, OH)4) and tiny f ...

Vegetation
Diversity of topography and geology provide excellent habitat for a wide variety of botanical species. The '' Kalmiopsis leachiana'' plant was discovered in 1930 by Lilla Leach in the Gold Basin area. The plant is a relict
A relict is a surviving remnant of a natural phenomenon.
Biology
A relict (or relic) is an organism that at an earlier time was abundant in a large area but now occurs at only one or a few small areas.

of the pre-ice age and the oldest member of the ''Ericaceae'' Family, and is the namesake of the Kalmiopsis Wilderness. In 2002, the nearly Biscuit Fire burned the entire wilderness area. The environment has changed dramatically and provides a unique opportunity to observe a natural response to fire disturbance through plant succession, erosional and depositional occurrences and changed habitat for flora and fauna. The Chetco Bar Fire re-burned large portions of the area in 2017.
