April category boards

Start from the discipline if timing is already decided.

These boards turn April into three entry lanes, so you can jump straight to the states that currently have the strongest mushroom, fossil, or detecting routes.

April metro radar

City hubs that already line up with this month.

Use these when the trip starts with a metro area and you need the fastest bridge back into timing-aware planning.

TroveRadar app companion

Research on the web. Keep the working plan with you in the field.

Keep the route, notes, and access context connected to your offline field workflow.

Offline notes

Keep species pages, find details, and trip notes available without signal.

Route memory

Pin promising zones, parking, and law checks before the day gets messy.

Field logging

Capture private finds, photos, and context while the details are still fresh.

Cross-device flow

Start research on the directory, then carry the same context outside.

Why are the monthly guides split by state and category?
Timing is local. A useful monthly guide has to narrow both the geography and the category so the advice reflects real seasonality instead of generic North American averages.
Do the event names represent official public events?
No. On TroveRadar monthly pages, event schema is used for recurring field windows such as scouting periods, exposure windows, and seasonal opportunities tied to that month.
What should you pair with a monthly page?
The best next click is usually a near-me page, a state guide, or a trail page because timing only helps when you also know where you can realistically go.
