Black River SF / Driftless WI North

700–1,400 ft · WI🚗 Directions

S

Black River State Forest and the surrounding north-central WI sand country — bridge between the Driftless Area to the south and the Northwoods to the north. Pine barrens (jack pine, oak savanna), oak-hickory ridges, and bottomland hardwoods (silver maple, swamp white oak) along the Black River. Spring morels in disturbed bottoms and dying elm; chanterelles in oak woodlands; matsutake-candidate Tricholoma magnivelare in jack pine; chicken-of-the-woods on red and white oak.

# Black River SF / Driftless WI North — S Tier | 2026-08-27 This region is locked in S tier because soil temp, sustained moisture depth, and volumetric water content have converged into a rare sweet spot—67°F soil with seven days of threshold-exceeding conditions and stable 0.18 VWC across the board. You're looking at 70+ viable species across all functional groups: choice edibles (Chicken, Hen, Hedgehog, Chanterelles), medicinals (Chaga, Reishi analogs), and wood-decay specialists (Turkey Tail, Artist's Conk). The absence of limiting factors is itself the story—this window won't last through early September as soil cools and late-summer desiccation sets in. Watch for a moisture dip in the next 72 hours; even a light rain event will reset the clock and extend peak fruiting another week. The Driftless topography means aspen and hardwood stands above 900 ft will fruit 3–5 days ahead of valley floors. **Hot tip:** Target north-facing oak and birch slopes right now for boletes and milk caps—they're 48 hours ahead of everywhere else in the region and will hold quality longer in the cooler aspect.
