I just came back from Abraham lake yesterday. Of course it's cold and windy. What disappointed me is my Gitzo tripod can't stand firmly on ice surface (no snow covered, just pure ice). I have Gitzo long spike set but it still can't just stand there. I should mention that this place never clam, it's windy all year long. That's why no snow covered on top of ice.
RRS has something called Rock Claw Foot, which is designed for rocky terrain. I think it might help on mirrored ice surface. However it didn't say it'll work with Gitzo tripod.
I wonder if some 3rd party parts out there can make my Gitzo stand on top of ice firmly. All I need is it stands there for 10 secs.
