Nugget Lake Park has lovely oddities
PLUM CITY -- Unless they were looking for it, most people probably wouldn't notice the unique geological formation stretching for four miles in eastern Pierce County.
But it's there -- and it's one of Nugget Lake County Park's most popular features.
The formation is known as the Rock Elm disturbance. Some geologists think the disturbance is an old meteor crater; others suspect either faulting or pressurized gas was the culprit.
