Remedial Investigation Field Activities in Military Reserve

The U.S. Army Corps of Engineers (USACE) has completed Remedial Investigation field activities at the former Boise Army Barracks, a Formerly Used Defense Site (FUDS) located near Boise, Idaho in 2023. The field activities will conclude the investigation to determine the nature and extent of (what, how much, and where) potential unexploded ordinance that may remain at the site due to past military use. Initial Remedial Investigation field activities occurred in 2019, 2020, and 2022. The investigation is part of a larger nationwide effort by the USACE to investigate possible environmental contamination at FUDS sites.

This 734 acre natural area is named for Fort Boise and the associated military maneuvers that were performed here between the 1860s and 1940s. The area served several purposes, including the staging of gunnery practice into the hills above. After the military halted its operations, the community recognized the importance of this area and the Boise Front for recreation and wildlife values. Boise City acquired title to the property from the Federal government for "recreation and public purposes". It is managed as a recreation and wildlife reserve, with human activities allowed in ways that do not detract from the natural values.

A Few Nice Options

#20A Bucktail Trail

Separation of Use – Bucktail Trail is open to downhill mountain bike traffic only. Uphill mountain bike access is via Central Ridge Trail. A new pedestrian-only trail named Two Point Trail has been constructed between Central Ridge and Bucktail Trail for hikers and equestrians.

#22 Central Ridge Trail

This trail, when combined with any number of trails in Military Reserve, makes a great loop. It affords wonderful views of downtown Boise and surrounding parts of this natural reserve. Best bet for fall color viewing.

#27 Cottonwood Creek Trail

Often referred to as "The Black Forest", you won't find any European castles, but you will find a pleasant and rewarding trail through cottonwood stands and open sagebrush flats. Please avoid the volunteer trails that meander through the brush as this area is set aside for wildlife to enjoy.

#25 Eagle Ridge Trail

Parts of this trail are surfaced with asphalt to serve maintenance of nearby communications towers. Because of this, the trail can be a good foul weather alternate and sports some fine views of the downtown area and a birds-eye perspective of Cottonwood Creek.

#20 Ridge Crest Trail

This trail links the Cottonwood Creek and Freestone Creek drainages and is part of the "North by Northwest" crossing of the lower reaches of the Boise Front. This trail should be avoided during winter months unless the temperature is below freezing as it is comprised of heavy clay soils that damage easily when muddy.

#23 Military Reserve Connection

This trail is part of the connection between Military and Hulls Gulch Reserves. This combined with the Kestrel and Red Fox Trails, is also part of the "North by Northwest" crossing of the lower Boise Front. Please stay on the trail since it crosses through a rare plant area.
