About Colorado Brass Survey Marker
The Colorado Brass Survey Marker is a surveying find from the 1800s-1900s era, commonly discovered by metal detectorists across the Central Rockies regions. Brass Survey Marker is a realistic Colorado detector target tied to mining camps, high-country resorts, and CCC campgrounds. Rather than pretending every state has the same history, this profile frames the signal around the kinds of sites that actually produce it in Colorado: beaches, town greens, camps, farmsteads, transport corridors, or old recreation grounds.

Colorado state guide
Metal detecting in Colorado is usually governed by who manages the ground rather than by one blanket statute. Municipal beaches and local parks may allow it, while archaeological sites, battlefields, historic structures, and many state park units are restricted or off limits. That matters in mining camps, mountain resorts, and park lawns.
