Gorgeous Stainless Steel Sculptures 

By Kevin Stone


Chilliwack, British Columbia-based Kevin Stone specializes in creating gargantuan, one-of-a-kind stainless steel sculptures. His towering bald eagle, called "Power and Authority," stands an astounding 20 ft high and has a massive 31 ft wingspan. He also completed an 85 feet long mirror polished stainless steel sculpture, the "Imperial Water Dragon." For almost two years, working seven days a week, he designed and created this 6000 lb, 12 ft high, 14 ft wide and 35 ft long dragon with two massive coils. It was made for River Rock Casino Resort in Richmond to celebrate the Year of the Dragon.
