Enjoy the exhibits at the volunteer-staffed visitors' center, then take a short stroll up the hogback to one of the most important dinosaur-track sites in the country. Dinosaur Ridge is a trip back 100 million years in time, to an ancient seaway populated by carnivorous megafauna. But it also offers a stunning view of the metro area's past and future: the remnants of the historic Rooney Ranch in the foreground, burgeoning suburban growth and Green Mountain open space battling for primacy beyond that, the city and the plains in the distance.
