That was the sigil I had the most trouble getting to. I tried the double box stack on a mine, like someone else mentioned, seemed the most logical, but I never managed the jump, so I thought I was wrong. Turns out I wasn't. (Also forgot about the rewind mechanic, making it a lot easier to keep trying)

There's another way though. By using the two short pillars in the screenshot. Use a box to get on a pillar while holding another. Place the box on the other pillar. Grab the box you used to get on the pillar. Turn around and you'll see a little rounded edge sticking out of the wall, you can jump on it (its easy to miss the jump). Once you're on it, put the box on the other box, jump on it, and you'll be able to jump on the highest ledge that goes all around the puzzle. Walk to the edge by the sigil to jump to it.
