Crane operator Albert Dyck lowers the boom so fellow Cliff’s Oilfield Hauling worker Bob Alford, left, and Royal Tyrell Museum paleontology technician Darren Tanke can lower a rowboat from the deck of the scow Peter C. Kaisen at the Kiwanis Picnic Park launch on the Red Deer River Tuesday. Named after an American Museum of Natural History paleontologist, Tanke built the scow last winter to recreate that museum’s groundbreaking trips down the Red Deer River to look for fossils and bone beds. Two dozen researchers, paleontology students and other dinosaur enthusiasts will take part in the five-week journey that ends at Dinosaur Provincial Park near Brooks in early August.
