Frozen Waters is one of the mementos that Harry Mason can pick up early on in Silent Hill: Shattered Memories. The memento can be found while searching through the woods adjacent to the town, hidden inside a container beneath a water tower south of the ranger station.
The memento is a transparent marble decorated by a green swirl inside and blue stripes outside.
The marble may allude to Cheryl Mason's persistent childhood naivety. The name of the memento also, like much of the game's imagery, alludes to ice and a state of being frozen, referencing Cheryl's inability to deal with Harry's death.
