Nome 2000, a partnership, owned a large tract of wilderness land in Alaska. The Fagerstrom family had used the property for camping and holidays since about 1944. In 1966, Charles and Peggy Fagerstrom marked off an area for a cabin and brought material to build the cabin, but never did so. In about 1970, they built a picnic area on the land, and in about 1974, they placed a camper trailer on the land, where it remained until the lawsuit. In 1987, Nome 2000 sued to eject the Fagerstroms from the land. The Fagerstroms had used the land only during the summer months. No one lived in the area during the winter months, when it was virtually uninhabitable. Has the family adversely possessed the land from Nome 2000?
