**Bighorn Mountains A-Tier: Post-Monsoon Flush Window** You're sitting in a genuine high-elevation flush—sustained soil moisture (0.21 VWC avg) paired with consistent cool temps have triggered 33 viable species, dominated by boletes, milk caps, corals, and agarics. The tier holds because moisture threshold was met and has stayed there for two weeks; that's the backbone of the rating. Hedgehogs, indigo milk caps, slippery jacks, and bay boletes are your bread-and-butter high-confidence targets—all conditions squared. The limiting factor is desiccation risk. At 52°F soil temp and only 0.25" rain in the last week, you're running on the fumes of that 14-day precipitation. Any sunny stretch above 8,500 ft will evaporate this window fast. Watch the next 36–48 hours; if temps stay cool and you catch any overnight drizzle, the flush extends another week. If high pressure locks in, you've got 3–4 days before the moderate-viability species start dropping out. **Hot tip:** Scout north-facing slopes and dense conifer stands at 7,000–9,000 ft where soil stays shadowed—those microclimates will extend your window by 5–7 days after the ridge tops dry.

⚠ 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.
