Grand Lake, CO sits nestled next to the largest and deepest lake in Colorado. It's full of rich log cabin architecture and charming shops and restaurants, but it has a surprisingly dark past. One of the more amazing houses in the area is nearly 150 years old and is called The Spider House, due to the intricate latticework of wood that decorate this two story log home. This home was built by Warren Greggs for his wife Mary and large family, but it would not bring them happiness.
