A newly completed 1.3-mile extension of the Dakota Ridge Trail near Morrison is giving hikers, mountain bikers and trail runners more mileage on the popular trails at Matthews/Winters Park. The new black-diamond trail on Dakota Ridge is “playful and bike-optimized,” said Eric Fields, trail team lead for North Jefferson Counties Parks and Open Space. Fields and his team designed the trail as a lollipop loop on the ridge’s south end.
