North Cascades

# North Cascades – S Tier | May 29, 2026 This is a **true morel season**—you're in the sweet spot. Seven straight days above soil threshold, sustained moisture (0.22 VWC locked in), and the snowline at mid-elevation guarantees fresh melt feeding the duff. Spring King Boletes and Red-Belted Conks are also live right now; the polyps have been activated and moisture is there to push fruiting. False Morels shadow the true morels perfectly, so cull carefully. The limiting factor is moderate desiccation risk—recent precipitation is solid (3.02" in 14 days) but last week's only 0.29" means you're not in a deluge window. Chaga, Birch Polypore, and the psilo complex are still in activation mode; they need another 3–4 days of sustained warmth before primordia set. Watch the south aspects above 5,350 ft over the next 48 hours—that's where the morel flush will concentrate as the melt front climbs. If we see another 0.5" precip in the next week, Chaga and the slower species will pop. **Hot tip:** Hunt the ecotone between snowmelt seepage and established duff—morels fruit densest where meltwater meets last year's organic matter, roughly 200–400 ft below the current south-facing snowline.
