Lewis & Clark NF / Little Belts

**Lewis & Clark / Little Belts – S Tier Call** You're looking at textbook late-summer mountain conditions: soil temps have settled into the sweet spot (60°F), recent moisture is adequate (0.99" over two weeks), and both oysters and boletes are primed to fruit. The S-tier rating reflects dual-species viability in the same window—a rare convergence at this elevation. Desiccation is the only real constraint; you've got maybe 48–72 hours before another dry cycle sets in, so elevation and north-facing slopes are your friends for extend longevity post-flush. Watch the forecast for any afternoon thunderstorm development over the Belts in the next 2–3 days; even 0.15" would reset the desiccation clock and lock in a second flush. **Hot tip:** Hunt north-facing subalpine fir stands above 7,000 ft where soil moisture lingers longest—boletes will cluster there while oysters take the slightly warmer transition zones.
