The links below are the same official sources the Club 49 map reads from. Bookmark this page; it is the tool bench.
BLM Mineral & Land Records (MLRS) is where every active mining claim lives; search before you dig. BLM GLO Records holds the original land patents back to the beginning, which is how you trace who first proved up the ground. BLM.gov and the Forest Service carry the office contacts and current closures. The Club 49 map draws claims and land status live from the same federal services.
USGS WaterWatch shows every river in the country as a colored dot against normal flow, the fastest read on whether your creek is workable. USGS Water Data is the deep well behind it, gauge by gauge. Weather.gov point forecasts beat any app in the mountains. The map carries all three as live layers, plus the Dig Window that turns them into green and red hours.
InciWeb is the official incident page for every named wildfire, closures included, check it before any summer trip. USGS Earthquakes runs the live wire the map listens to.
Each survey is the deepest bookshelf on its own ground: California, Washington (DNR), Oregon (DOGAMI), Idaho, Montana (MBMG), Arizona, Utah, Texas (BEG) and Colorado. District reports, bulletins and maps that never made the internet twice.
Washington runs hand prospecting under the WDFW Gold and Fish pamphlet; California stream rules live with CDFW; and every state guide on this site (see the sitemap) summarizes its own state's quirks. When in doubt: the map shows ownership and claims, the agency shows the season, and permission beats forgiveness everywhere.
