South Platte headwaters and Tarryall Creek drainage. Mixed lodgepole and spruce. Good porcini and king bolete habitat. Less crowded than northern Pike NF.

**Pike NF South / Tarryall – Tier A Breakdown** You're looking at a textbook late-August sweet spot: sustained soil moisture (0.32 VWC, stable across 7 days) in a region with zero drought stress and 1.52" of recent precipitation have unlocked 33 high-viability species simultaneously. The bolete, russula, and agaric families are all firing at once—Bay Bolete, Painted Bolete, Chicken-Fat Bolete, Lobster Mushroom, and Slippery Jack are your bread-and-butter targets. Soil temps at 53.6°F sit right at the threshold for most species, so you're not heat-limited; moisture is your asset and your only real risk. The limiting factor here is **desiccation risk**—those moisture conditions can flip fast at elevation in late August as diurnal heating increases. You've got roughly 3–5 days before a dry pattern or temperature spike could collapse your window. Cauliflower and Reishi remain marginal (soil temp just below their sweet spot), but everything else is go. **Hot tip:** Target north-facing slope sections and shaded conifer pockets in the morning—they'll hold overnight moisture longest as the day heats up.

⚠ 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.
