What the record shows
The federal survey describes the site: Now beneath Trinidad Lake
Sopris Plaza appears in the U.S. Geological Survey's place-name archive as a historical populated place — a settlement that once carried a name and no longer does. Our editors are verifying its full story against census records, newspaper archives, and county histories; this record will grow as sources are confirmed.
Before you visit
Unverified sites may sit on private land, and coordinates from historical records can be imprecise. Verify land status and access before traveling. Take photographs, leave nails — removing artifacts from federal land is a crime.
