Northern Colorado mountains. Routt NF has heavy snowpack and late-season moisture. Strong king bolete and chanterelle habitat in mixed spruce-aspen. Steamboat Springs as base.

**Steamboat / Routt NF – Tier A, Late May Peak Window** You're in the sweet spot: soil temps have crossed the 54°F threshold consistently, moisture is locked in at 0.26–0.27 VWC, and snowmelt is providing steady hydration. True morels are your A-tier target right now—7 consecutive days above trigger means mycelium is actively fruiting. Spring kings and red-belted conks are equally viable; the latter especially favor the cooler north-facing slopes still near snowline. The single constraint is desiccation risk (high). This isn't a moisture problem—it's wind and sun exposure. Morels and kings fruit in the next 3–5 days if conditions hold, but they'll abort fast under dry winds once they've pinned. Night temps and cloud cover are your friends here. Watch the afternoon humidity drop; if it bottoms out below 40%, fruits will mummify before they mature. The snowline's still high enough that north-facing pockets above 9,500 ft will stay moister longer. **Hot tip:** Scout the transition zone where snowmelt keeps soil damp but canopy cover blocks direct sun—that's where your morels will flush hardest and persist longest.

⚠ 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.
