Ollin Magnetic Digiscoping System

If you have a spare half hour . . . .

Thanks for sharing! I drove through that area this past Fall and wish I had seen this documentary prior to that. I knew what the overpass’ function was, but has no idea it was a migration corridor.

I saw several of these overpasses in Banff NP. That’s a really cool place too!
