Hey, that sounds epic. For a tripod that can hold its own on ice, you’ll want three legs that spread wide, about a foot apart, so you get a stable base. Each leg should be a hollow metal tube so you can fill it with gravel or sand to weight it down. If you can, attach a small crampon‑style spike to the bottom of each leg so they bite the ice. The top arm should be adjustable, maybe a simple rack‑and‑pinion joint so you can tilt the camera up or down. Keep the whole thing light but sturdy, and remember to use a tripod head that can lock tightly – a quick‑turn lock works best on uneven ice. If you need help cutting the tubes or threading the bolts, just bring your lucky wrench over, but I’m not lending it out— it’s too important for the job. Good luck, and watch out for those slick spots!
