# Steamboat / Routt NF (A-Tier) — 2026-08-27 You're sitting in a rare window: soil temps are optimal (69°F), moisture is locked in across seven consecutive days at 0.21–0.22 VWC, and the moisture trigger has fired. This is why the tier is A. The species list reads like a forager's dream—everything from Cauliflower and Hedgehog to Lobster, the full bolete/russula suite, and premium finds like Reishi. The elevation (7–10k ft) and late August timing align perfectly with the high-altitude flush cycle. The catch: desiccation risk is flagged as high. That sustained 0.21 VWC is fragile; minimal recent precipitation (0.08" in seven days) means you're living on stored snowmelt and subsurface moisture. A dry front or three consecutive 75°F+ days will evaporate your window fast. Get into the field now, especially on north-facing slopes and in shaded conifer understory where evaporation lags. Prioritize Cauliflower, Hedgehog, and Lobster—they're bulletproof and command premium prices. Check the forecast obsessively; if the next 48 hours stay cool and overcast, this remains A-tier. Sun + heat will crater it to B by Friday. **Hot tip:** Work wet pockets in Engelmann spruce-subalpine fir transition zones (8–9k ft north aspects)—they'll hold moisture longest as drying pressure builds.

⚠ 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.
