▸ Provide a choice of paths
Present the proverbial fork in the road and ask them which way they go. There might be other paths, and they might do something different, but you're presenting the obvious options and prompting them to choose.
Try to give them some indication of how the options are different. Otherwise, their choice isn't meaningful.
The available paths don't have to be literal paths, or they don't both have to be. For example, the choice could be between stopping and exploring this ruin, or pressing on towards their destination.
As a hard move, provide a choice between paths that they don't want to take.
"The cave is maybe 30 or 40 paces off to your right, no sign of movement around it. But, Blodwen, you spot tracks in the snow. Big ones, leading from the cave and off to your left. What do you do?"
"Okay, the sleds are loaded. Are you going to head back the way you came? The crinwin will almost certainly notice you if you do. Or you could cut deeper into the Woods and try to circle around them, but that'll take longer. What do you do?"
"As hard as you push yourselves, by the time the sun's almost set, you're still a good half-hour away from town, maybe more. Do you press on, traveling in the dark? Or do you start looking for some place to spend the night out here?"
