Meanwhile, in Surprise Valley, Venters and Bess are preparing to leave as Jane and Lassiter departing, except on burros. Lassiter sets fire to Withersteen House and flees on horseback with Jane. They encounter Venters and Bess in travel. Before they part, Lassiter explains that Bess is not really Bess Oldring, but actually Elizabeth Erne, the lost daughter of Milly Erne.
Jane gives Venters her horses, Venters and Bess gallop for Venters' Illinois home, and Lassiter and Jane find refuge in Venters' valley paradise. On the way, Lassiter rescues Fay, but they are pursued to Surprise Valley. As Tull and his men begin to climb up the cliffside, Jane shouts to Lassiter to "roll the stone," which he does. The ensuing avalanche closes the outlet to Deception Pass "forever." (This is, of course, not true, as Jane, Lassiter, and Fay return in Grey's sequel, The Rainbow Trail/The Desert Crucible.)
