**S-Tier Window: Hedgehogs, Milk Caps, and Boletes Own This Elevation** The Tetons are firing because sustained moisture (0.27 VWC across 7 days) has stabilized at altitude just as soil temps stabilized around 53°F—that sweet spot where your high-viability species (hedgehogs, indigo/saffron milk caps, bay/painted/chicken-fat boletes, plus lobster and slippery jacks) all light up simultaneously. Twenty species are flagged high-confidence; the moisture trigger holds and there's zero drought stress. The moderates (cauliflower, Reishi, Chaga, birch bolete) are edge cases—soil temps haven't crested their 55°F minimum yet, so they're watching. Moderate desiccation risk is the only brake: late-August sun and thinner air at 6k–13.5k feet will desiccate flush fruiting bodies fast if you're not methodical with timing. Hit the shadier north-facing draws and subalpine forest before 11 a.m.; afternoon thermals will shred exposed populations. Watch for a cooling trend or precip bump in the next 3–5 days—either locks in a second flush, or you've got a narrow harvest window that closes hard. **Hot tip:** Lobster mushroom parasitizing milk caps in the 8k–9k band on north aspects is your highest-volume play right now—they'll hold moisture longer than solitaries and are hardier to desiccation than hedgehogs.

⚠ 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.
