Soil warming to ~50°F at the retreating snowline, ~1 to 3 weeks after snowmelt; first-spring burn scars flush hardest, and the front marches uphill through the season.

Managed, mind the rules
Often a single flush after fire: take what's up and cut cleanly; little you do harms next year's crop. Stay out of closed burn units.
The read
Spring crown jewel; flushes in mountain burn scars and river valleys as snow melts.
The event: Soil hits ~50°F at burn scars as the snowline retreats.
Field notes
Spring, 1–3 weeks after snowmelt as soil reaches ~50°F. Best in the first 1–2 years after a wildfire ('burn morels'); also cottonwood river bottoms and dying elm/ash. South-facing slopes warm first.
Fresh morels are firm, springy, and completely hollow when halved (confirm the ID and evict the slugs while you're in there). Pass on any that are soft, collapsing, waterlogged, or sour-smelling. Morels rot fast, and spoiled ones will turn your stomach even fully cooked. Look for a clean, pale interior; dark and wet inside means it's gone. Small, tight morels travel and keep better than big brittle ones. Never eat one raw.
False morels (Gyromitra, Verpa) carry gyromitrin and can be lethal. True morels are completely hollow inside with the cap fully attached to the stem; false morels have cottony/chambered insides or a cap that hangs free.
Personal use generally needs no permit on public land (~1 gal/day typical). Burn-area harvest may require a free permit and have active fire/access closures. Check the specific forest.
Always cook thoroughly: raw or undercooked morels are toxic, and don't pair them with alcohol the first time. Confirm true vs. false morel every time.
Always fully cooked. Halve lengthwise to confirm the hollow interior and evict insects, soak briefly in salt water, then sauté in butter. Peerless in cream sauces. Dry to preserve; the flavor intensifies.
