Alpine Lake you're following a lead that came from a bird.

Um, yeah!!  Waterfalls are way interesting.  If it's a little one you can even ride it down.  Maybe meet the river spirit who lives there, she replied with a smile.  She'd slid down a few for fun here and there, though the optimal rock and water layout was hard to find.  They were at least pretty if nothing else.

Who taught you that trick? Watchin the water and all.  It's good.  It would have never occurred to her to check the current's speed to find a fall, though now it seemed pretty obvious!
