Rising Sun Valley annual rate of return

For @Peregrine (and again, if Ebony wants to hop in with @Lasher, that's cool).

No idea what to call it, but I figured they could passively name it. :)

South, far south, they had gone, and then taken a sharp turn to the east. The familiar landscapes brought memories back to Fox. Memories of being a sole leader of a pack, and feeling like she was at home. But they were only memories. Peregrine, Blue, and Dante now ruled alongside her. From now until the day she died, she would not be a sole leader. Her place was at Peregrine's side, no matter where their feet took them today (or tomorrow, or any of the days after that).

The trio was now east of Wapun Meadow and Blackfoot Forest, and they had just crested a hill to see a rather magnificent sight below them. A tall, pine forest sprawled out before them, with a wide, lazy river flowing from north to south. But that wasn't even the most prominent thing in sight. On the other side of the flat, level forest jutted a mountain. It looked as if somebody had stepped on a wobbly rock, and one end had gotten stuck in the earth, leaving a large, exposed jagged edge that kicked its way out into the world. Fox had never been a particularly good judge of distance or height, but she could tell by the way the clouds brushed up against the landscape's top, it was a true mammoth.
