What’s in a Name?

When Lena Yock, the matriarch of the Yock family, bought 160 acres near Fish Creek in 1903, it came with a cabin that was presumed to have been built around the turn of the century. Over the years the dilapidated cabin stood unnoticed next to the icon More Barn that has become synomous with Steamboat ski area. Then, in 2010, a historic preservation project was launched and the Yock cabin was restored by disassembling and rebuilding the homestead one labeled log at a time.
