 * Naming convention for `RIVER`/`POOL`: directions indicated are flow of river
 * (e.g. `RIVER_SOUTH` indicates a river that flows south through entire block,
 * `RIVER_WEST_SOUTH` indicates a river that flows west and then south, etc.)
 *
 * Naming convention for `CLIFF`: direction indicated is side with valley
 * (e.g. `CORNER_RIGHT_TOP` indicates the top part of a corner cliff
 * with the valley on the right). However, directions for border cliffs simply
 * indicate the side of the map.
