4,500–8,678 ft · MT🚗 Directions
Lewis & Clark National Forest — the Little Belt, Big Belt, and Highwood Mountains across north-central Montana. Mixed lodgepole pine, Engelmann spruce, subalpine fir, Douglas fir, and aspen. Showdown Ski Area, Kings Hill, and the Smith River corridor for access. King boletes and lobsters after July-August thunderstorms; morels follow spring burns in lodgepole.

**Lewis & Clark / Little Belts – Tier A Actuation Window** You're in peak true morel season with textbook conditions: soil just crested 57°F, sustained moisture averaging 0.19 VWC over seven days, and zero drought stress. Oysters are equally viable and often overlooked at elevation—both species are fully triggered. The catch: desiccation risk is *high*, meaning morning moisture windows are narrow and afternoon evaporation will shut down fruiting fast on exposed south aspects. North-facing benches and shaded creek drainages will outperform by a full day's stretch. Two percent of normal snowpack gone cleanly; don't chase the higher elevations looking for lingering snow cover—that's dead water. Stay in the 5,500–7,000 ft band where soil heat is maximal and shade still buffers wind. **Hot tip:** Hunt north aspects and riparian corridors at first light—the desiccation window closes by 10 a.m. once the sun hits.

⚠ 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.
