Trail Overview
Forest Road 3924 runs from its intersection with FS 3903 to its intersection with FS 3905. This is one of the few two-track dirt trails in Forest County that is open to ATV and SxS traffic, rather than just 4x4 and full-size traffic like many others. While this trail is not super technical, it does offer a different driving experience than that of many of the other trails in the area. This trail is a two-track dirt trail, with marginal ditch lines on each side. These ditch lines are full of undergrowth, but the undergrowth remains relatively short, aiding in sight lines and also allowing for a spot to pull off for oncoming traffic to pass. Surrounding the trail is a relatively sparse forest, which allows for excellent views of the surrounding landscape. Elevation changes on this trail are very minimal and limited primarily to a gentle downhill grade when traveling south. The trail surface is hard-packed dirt, which can become muddy during and after rainfall. Expect to make small ruts or see small ruts depending on the weight of vehicles using the trail. Cell service in this area is generally acceptable, and downloaded maps are not needed but should still be considered if traveling elsewhere in the region.
History
Argonne Experimental Forest features the largest contiguous tract of old-growth hemlock hardwood forest on drumlinized ground moraine. These types of protected rich mesic hardwood forests are very scarce in northern Wisconsin and on this land type (Argonne Outwash Plains). A northern hardwood forest dominated by sugar maple, hemlock, yellow birch, and basswood is located on a gently sloping, unpitted outwash fan. Shrubs include leatherwood and elderberry. Understory plants include oak fern, ground pine, wood ferns, rosy twisted stalk, Canada mayflower, running club-moss, lady fern, and sweet cicely. This area is surrounded by a conifer swamp, which has several rare species. The conifer swamp is dominated by black spruce, tamarack, and white cedar. Understory species include Labrador tea, leather-leaf, balsam fir, yellow bluebead lily, false mayflower, creeping snowberry, Canada blueberry, and sphagnum. Rare species include small round-leaved orchis, sparse-flowered sedge, and northern bog sedge. The extensive habitat of Argonne Experimental Forest supports uncommon boreal bird species such as boreal chickadee and gray jay. In addition, the rare three-toed woodpecker (Picoides tridactylus) has been seen in the conifer swamp. Other birds include broad-winged hawk, blackburnian warbler, and scarlet tanager.
