The enterprise failed, and the bison migrated to the south finish of the House Rock Valley space. In 1927, the herd was offered to the Arizona Game and Fish Department.

For some time, the herd wandered between the park and the space now often called the House Rock Wildlife Area. Since 2009, most of the bison have settled down inside the park.

“The bison, they’ve become relatively aware of the fact that when they go beyond the park boundary, they are at risk from the state-led hunt,” Ms. Thomas stated. “So that’s why you often see them almost exclusively ranging inside that small area.”
