The name has different explainations, and one might be as good as the others.
Karen Prestgard who lived here and was with and ran a school for weaving, said simply that Kruke means; where it grows nice grains and corn in this sense is barley.
Ivar Kleiven, village historian from Vågå, says that it is because the river in the old days made a hook when it changed direction.
Kleiven has another explanation; Kruk is the lower sheaf on kornstauren, when drying grain by attaching one by one sheaf superimposed on a pole.
Oluf Rygh, name specialist believes that Kruk is room to store inside your fist when you put your fingers over the cavity.
Ivar Teigum, book author, looks at Kruk placement in the farm row right in the middle of Heidal on a bounded
terrace on the gentle terrain.
There are still unsolved mysteries of some of the names of places on the farm. Why the name "Husdalen",
which is used in the area at the top of the field?
