First a crazy idea…
Carry a 12 oz Scandium framed 357 revolver. It doubles as minimalist bear protection. Shoot the ice and let it shatter (use lead free ammo for health and weight savings). Don’t forget ear protection!
More serious idea…
That looks tough. I’m assuming that water is freezing as it comes out of the ground. There may not be much flow anywhere so the ice screw and suction filter might not work.
I think the best solution would be a hammer or hatchet to break it up and a larger pot to melt it in. Not the lightest but possibly the more efficient. Maybe a suction filter as well for when you do have some running water.
Extra weight to increase efficiency during the limited daylight hours is probably worth it in the situation. Also if you’re able to drop caches you might leave hot water in a cheap thermos. It might still be liquid when you get to it.
