The first primitive crossing over any river on the North West Coast is believed to have been the "Sawdust Bridge" which was put across the river adjacent to (and not long after) a sawmill was fully operational in 1854. The bridge became known as the Sawdust Bridge, not because it was built of sawdust, but because it was adjacent to vast deposits of sawdust which were flumed along the banks of the Don River. Users were able walk on the sawdust heaps to access the footbridge. This is at least the fourth incarnation of the bridge, the previous one being a Bicentennial Project linking the rebuilt causeway to the eastern shore, while the current high tech bridge of June 2017 was flown in parts and positioned by helicopter.
The log is in a camouflaged silver bison, but this might not be quite as straight forward as looking for this little container alone. The clue might help, and it is in plain sight. We hope you appreciate it, and replace carefully bearing in mind this is potentially high muggle territory. Only room for log, no pencil, nothing else.
