Yesterday, the old Biggar Cabin moved to Arvada. In pieces. A puzzle project for Troy of the Arvada Historical Society to put together. This is actually a 3-sided outbuilding, not the main homestead cabin.
In photo 1, Troy and DeWayne are unloading the old logs. The Arvada Flour Mill is in the background.
Photo 2 shows the intriguing notch pattern. Top notch here shows convex V parallel to the length of the log; notch below is concave V and perpendicular.
