This is the Dittli-Lanz cabin on the Russian River in California. This view of the cabin is from the street. You can see the stairs leading up to the big porch, from which the house was entered. The door to the basement is behind the porch post, between the two windows.
Grandma Lanz is on the little porch. Gandpa Lanz has the baby carriage. You can guess who the baby is.
