Joan is just visible above the wall at the top of the cascade. Buchanan is at the bottom of the cascade just right of the pool. Dante is on the same side of the park, just up the hill from Buchanan. Serenity is at the top of the cascade on the left side of the park a bit farther north than Joan.
Notice the Washington Monument in the distance (lower right). Also notice, as is visible in several other photos too, that her sword has been broken off (as of 6/2006).
