Black Hills National Forest
Deerfield Trail gradually descends from west to east as it follows the scenic canyons of Slate Creek and Rapid Creek. You'll pass historic Flanigan Cabin, trace the route of an old flume and follow the old rail line into Silver City, before climbing again to meet the Centennial Trail just off US 385.

Length: 28 miles in both trails
Elevation: 4600 to 6000

10 mile Lake Loop Trail circles Deerfield Lake, known for its excellent cold water fishing. Four trailheads provide easy access. Tall pines shade the trail south of the lake, while to the north the country opens up as the trail skirts the edge of Reynolds Prairie, one of three large natural meadows in the Black Hills.
18 mile Deerfield Trail runs east from the lake, connecting with over 200 miles of trail via the Mickelson and Centennial Trails. Five trailheads provide access at intervals of 3 to 9 miles.

This 28 mile, all season, non-motorized trail complex connects the Deerfield recreation area with the rest of the Black Hills on more than 200 miles of trail, including the Centennial Trail and the George S. Mickelson Trail.
Hikers, mountain bikers, horse riders and cross country skiers can enjoy the trails, although not all trail sections are suitable for all uses.
Eight trailheads provide convenient access at intervals of one to nine miles. You can plan trips of an hour, a day or several days. Both trails are marked with brown posts bearing distinctive logos, and are easy to follow.
In addition to great scenery and abundant wildlife, you'll pass by a variety of historic sites including a log flume, cabins, mines, tunnels and railroad grades.
This narrative describes the route and attractions along both trails, traveling from west to east.
Deerfield Lake - 10 miles
Lake Loop Trail makes a 10-mile circle around Deerfield Lake, a 414 acre reservoir at 5900 feet elevation. From Reynolds Prairie you'll have great views of the lake. To the south, the trail winds through tall pine forest and small meadows. Lake Loop Trail is well suited to all non-motorized uses. You can camp, picnic, fish, swim and boat at Deerfield Lake. There's a fee for camping. At the west end of the lake, 9-mile Fen Trail , a popular horse route, takes you up Castle Creek to wet meadows that support unique plant life.
Deerfield to Mystic - 6 miles
Kinney Canyon below Deerfield Dam is a walk-in trout fishery on Castle Creek. Staying on the main trail, you'll reach Kinney Canyon Trailhead in about a mile. East of there the trail reaches its high point of 6200 feet in Slate Prairie, before dropping down Crooked Creek and Whitetail Gulch to Mystic Trailhead. Here, you'll connect with the George S. Mickelson Trail, now under construction by the South Dakota Dept. of Game, Fish and Parks. Just north are the Castleton dredge mining sites and Mystic, a mining camp turned railroad town. The old Mystic CCC Camp is just south. This part of Deerfield Trail is suitable for all non-motorized trail uses.
Mystic to Slate Creek - 6 miles
East from Mystic Trailhead, you'll follow the old Grand Island & Wyoming Central Railroad (later the Burlington Northern, and now the George S. Mickelson Trail. The trail passes through dense hardwoods including aspen, birch and alder before making a fairly steep climb up Lind Gulch to the south. Crossing into the Slate Creek drainage, you'll pass close to Slate Creek Dam, another good fishing spot. The country changes dramatically now, as the trail turns north and enters the sheer walls of Slate Creek Canyon for the next three miles. You'll pass Black Tom Mine, Flannigan Cabin and the Warren-Lamb flume, which carried logs to the railhead near Canyon City in the 1920's. Hikers will cross Slate Creek 34 times on slab-sawn log bridges; horses can cross almost anywhere. This section of the trail isn't recommended for cross country skiing because of the numerous stream crossings.
Rapid Creek - 3 miles
This level section of trail, at an elevation of just over 4600 feet, is the easiest on the whole trail. White spruce and ponderosa pine tower over the now quiet Rapid City, Black Hills and Western rail line. You'll follow this easy route, also called the Crouch Line, from west of Canyon City downstream to Silver City. This roadless stretch of Rapid Creek is a popular walk-in fishery known for its nice brown trout. Even if you don't fish, you'll enjoy the natural beauty of this deep, rocky canyon. Silver City Trailhead is at the end of the road, just west of the town of Silver City. This section of trail is suited to hikers, bikers and horses, plus families with young children and older walkers. Wide wood bridges cross the creek several times. You can cross country ski when snow conditions permit.
Silver City to Deer Creek Trailhead - 3 miles
Below Silver City the canyon widens and Rapid Creek empties into Pactola Reservoir. The trail passes near Jenney Gulch Picnic Area and then makes a long gradual climb through the pines to Deer Creek Trailhead on the Silver City Road just off US 385. A Deer Creek you'll connect with the 111-mile Centennial Trail, and you'll have to make a choice north toward Boxelder Forks, Dalton Lake and Bear Butte, or south to Sheridan Lake, Black El Wilderness, Custer State Park and Wind Cave National Park. This east end of Deerfield Trail is open to all non-motorized travel, although cross country skiing might be marginal. Black Hills National Forest Visitor Center is close by, on the south end of Pactola Dam. The center is open in the summer and has informative exhibits on Black Hills natural history.

Along the Trail
The Custer Expedition explored and mapped the Black Hills in 1874. The Expedition camped on Castle Creek at what would later become Deerfield. In 1876, Gen. George Custer and his Seventh Cavalry troops were killed at the Battle of the Little Bighorn in Montana.
Deerfield , first called Mountain City, was the site of a brief gold rush. Deerfield's store, school, post office and other buildings were moved in the 1940's to make way for Deerfield Dam.
Mystic and Castleton were founded in the late 1800's as mining camps. Later the railroad came through both towns.
Railroads were the preferred way to travel through the Black Hills for two generations. The Dakota, Wyoming and Western line was formed in 1901 to provide a direct rail link between Rapid City and the central Black Hills. The line up Rapid Creek required more than 100 bridges in 37 miles. The line was completed to Mystic in 1906. It operated as the Rapid City, Black Hills and Western until closing in 1947, but it's still called the Crouch Line in honor of its builder and first owner, C. D. Crouch.
Canyon City , located on Rapid Creek just below the mouth of Slate Creek, was the site of gold placer mining in the 1880's and '90's.
Silver City , originally called Camp Gorman, was home to 300 people who worked the mines and logged the native timber. Miners took gold, silver, antimony and quicksilver (mercury). A hydropower plant built in 1898 provided power to Rapid City. An even larger plant with a three mile flume was built in 1907.
Pactola Valley included the community of Pactola, Camp Wanzer (a health facility for TB patients), and CCC Camp Pactola. The name "Pactola" derives from the River Pactolus in Greek mythology. When Pactola Dam was built in 1956 these historic sites were buried under the reservoir.
