It's speculated that the forest and water temples in Ocarina of Time were originally wind and ice temples. The symbol on the Water Medallion from the Water Temple appears to have a snowflake on it, and the Forest Medallion design resembles a fan. This connection is further supported by the interior of Ganon's Tower, which is based on different temples. The Forest Temple portion of the tower has a wind puzzle based around fans, and the Water Temple portion of the tower is based on ice.
