110 Acre Dream Farm Buried by Sea of Mud
Castle Rock Washington report on Sam and Ann Hornstra who moved from southern California dairy operations to a 410 acre site near Interstate 5 and Castle Rock in 1978. Mount St Helens eruption left most pasture, corn and hay covered in mud, killing 650 filberts and 150 walnut trees, leaving only 20 acres usable. They saved 22 cattle from 75 to 80, board 50 head in Oregon, and recall the river mud, steaming and eels jumping, while planning rebuild efforts.
