600–1,979 ft · MI🚗 Directions
Michigan's Upper Peninsula. Vast mixed hardwood-conifer forests of sugar maple, yellow birch, hemlock, and aspen. Ottawa and Hiawatha NFs provide extensive public land. Latest morel season in MI — often running into late May.

**Tier A—Full Flush Window, But Watch the Dry** You're sitting in a genuine sweet spot: 73°F soil, sustained moisture above threshold for a full week, zero drought stress. The moisture trigger is *locked in*, which means everything from choice edibles (Chicken of the Woods, Black Trumpets, Parasols) to wood-decay specialists (Turkey Tail, Artist's Conk) and boletes (Aspen, Birch, Frost's) are all producing simultaneously. This is the rare window where species diversity actually peaks because temperature and soil water are both optimal and stable. The single constraint is *desiccation risk*—high. That 0.09" over the last 7 days is razor-thin. You're living off residual moisture from the 14-day total (0.99"), but that reservoir is finite. No rain in the next 48–72 hours will crater your productive window. Prioritize ground-fruiting species *now* (Chicken, Parasols, Puffballs, Boletes)—they're already popping and will abort hard if the surface dries. Wood-decay fungi (conks, polypores) are less time-sensitive and will keep. Avoid the roadside; hunt shaded ravines and north-facing slopes where soil moisture persists longest. Hot tip: Scout your best aspen and birch stands *tonight*—if no rain hits by mid-afternoon tomorrow, the boletes will vanish in 36 hours.

⚠ Road Access Notice
Always verify road access is public before following GPS directions to mountain areas. Many forest roads are seasonal, gated, or require 4WD. Dispersed camping follows USFS/BLM rules (typically 14-day limit). Check ranger district offices for current road and campground conditions.

Primordia readiness: Cold = mycelium dormant. Activating = soil warming, primordia building. Primed = 5+ sustained warm days at species threshold; fruiting imminent if moisture cooperates. Based on Schmidt 1983 / Mihail 2007.
