Bridger-Teton NF and Grand Teton NP buffer. Dense spruce-fir and lodgepole. Excellent king bolete territory. Significant foraging community near Jackson Hole. Deep snowpack.

**Bridger-Teton A-Tier: High-altitude boletes and amanitas are *live right now*—moisture window is narrow.** You're at the sweet spot where sustained soil temps finally cleared the 54°F threshold and VWC held steady at 0.20 over a week. That 0.81" in the last 14 days got you here, but yesterday's near-zero precipitation means desiccation risk is your hard ceiling. The Indigo Milk Caps, Bitter Boletes, Chicken-Fat Boletes, and both Amanitas (Coker's and Panther Cap) are all conditions-met right now—these are your A-tier targets. Everything else is marginal on temperature; True Morels and the soil-dependent species (Reishi, Chaga, Birch Bolete) are 1–2 days away from dropping back. The limiting factor is moisture holding power at elevation. You have zero SWE to feed the system going forward, so this window closes the moment you see a dry day stretch longer than what's already baked in. Watch the next 72 hours obsessively—any rain, even light, keeps the boletes alive; any continuation of current dryness collapses your viable window fast. **Hot tip:** Work north-aspect slopes above 9,000 ft where snowmelt seep is still active and soil stays coolest; boletes fruit longer in those microclimates when VWC is this marginal.

⚠ 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.
