Sue thankfully had her camera along.
We could only assume this was a bear track!
So I went to the web to compare and it is pretty clear it is, here is an example:
How to tell bear droppings apart:
We advise the outdoorsman to wear little noisy bells on clothing so as to give advance warning to any bears that might be close by so you don't take them by surprise.
We also advise anyone using the out-of doors to carry "Pepper Spray" with him in case of an encounter with a bear.
Outdoorsmen should also be on the watch for fresh bear activity, and be able to tell the difference between black bear feces and grizzly bear feces. Black bear feces is smaller and contains lots of berries and squirrel fur. Grizzly Bear shit has bells in it and smells like pepper.
