Angeles NF / San Gabriel Mountains

**Angeles NF Tier-A Reading – 2026-07-13** The A-tier rating reflects available fruiting potential despite bone-dry conditions—you've got thermal energy and no active drought stress, but you're operating on fumes. All eight viable species are moisture-marginal; the 0.13 VWC is just barely functional for fruiting, meaning you're looking at a narrow window before desiccation stress shuts production down entirely. Stinkhorns dominate the roster because they're thermophilic and can push fruit bodies faster than oysters or psilocybes in marginal moisture—they'll abort less readily if conditions stay tight. The real limiter is that zero precipitation over 14 days; without a rain event, this viability window closes in 3–5 days as soils dry further. Scout north-facing aspects and any seepage zones above 5,000 ft where subsurface moisture persists longer. Watch tomorrow's forecast obsessively—even 0.25" of rain resets the clock and pushes this to genuine productivity. **Hot tip:** Hit the stinkhorn beds at dawn while dew is still present; they fruit fastest in this window and won't wait for ideal conditions.
