Thaw -

At the end of the canal an isolated lock opens and closes its gates in accordance with the tides. A whole city in exile rushes here, packing the boats, fleeing the drowned valley.
Although the rain did eventually stop, the ground kept dissolving.
On the other bank, at the edge of the forest, a young woman appears. She seems to have come from a long journey and is determined to continue. She gets into the water to cross.

Ice jam -

The lock has long since carried on its work alone in the submerged valley, but its monitoring circuits reactivate and search the basin. It would seem that a woman came there.
Clinging to the shelter for a break, a breath, a respite, she prepares to go out. Sounds from outside reach her: everything is moving, everything is gone. She has stayed. She is going to run.
