Bighorn NF. Isolated range with lodgepole pine, Engelmann spruce, subalpine meadows. Good king bolete habitat at mid-elevations. Late-season morels in high burns.

**Bighorn A-Tier Breakdown** You're looking at a textbook early-summer sweet spot: soil temps at 63°F hitting the mycological goldilocks zone, and seven solid days of sustained moisture above threshold. The full Tier A slate is live—Reishi, Birch Bolete, The Prince, Scaly Wood Mushroom, all the choice edibles and specimens are primed. Even the toxic species (Panther Cap, Coker's Amanita, The Sickener) are nodding, which tells you the substrate conditions are genuinely dialed. The catch: **desiccation risk is high**. You've had only 0.3" in the last week and 0.41" in two weeks—that's spare. The 7-day VWC average of 0.22 is solid, but you're teetering on the edge of evaporative stress, especially at elevation where UV and wind are relentless. This window is *now*—don't wait for the next forecast. Focus on north-facing slopes and riparian zones where soil stays cooler and seepage maintains moisture longer. Expect the open south-facing flats to dry hard by late afternoon. **Hot tip:** Hit the subalpine birch groves (11,000–12,500 ft on north aspects) hard—Birch Boletes, Birch Polypores, and Reishi will fruit heaviest where shade retention meets soil moisture, and you've got maybe 48–72 hours before desiccation collapses the flush.

⚠ 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.
