While heartbroken over the loss of Edith, Bert continued on at the South Rim. He immersed himself in the work of breeding and training horses on his homestead and raising his three children.

The establishment of Grand Canyon National Park in February of 1919 brought many changes to the local community. Fred Harvey was authorized to run all Grand Canyon concessions, and the battle with Bass was over with Harvey as the victor. In 1923, William Wallace and Ada moved to Wickenburg, and by 1926, all of Bass's property at the Grand Canyon had been sold, thus ending an era of competitive enterprise at the rim.

In 1927, Bert married Rosa White, the school teacher at the Grand Canyon school. (She later taught at the Anita school, not far south of Grand Canyon Village). Rosa remained Bert's wife and loyal companion until his death.

Ranching and horse breeding were a way of life in the West. Bert Lauzon was knowledgeable about both and did them well. He kept a sizable herd of horses and often sold or rented them to the Park Service. A few horses, such as Governor Hunt, named for his friend and former Arizona Governor, George W.P. Hunt, stand out as his personal favorites.

The Lauzon children all learned how to ride, and Hubert and Loren worked in ranching activities and experienced the out-of-doors, the clear skies, and the feel of the saddle along with plenty of hard work when they were young.

The rodeo was, and still is, a part of the western way of life where cowboys test their mettle and skills by riding, racing and roping. Bert, Hubert, and Loren Lauzon participated in the activities of the early rodeo events at the Grand Canyon.

Wild horses roamed the plateau region by the Grand Canyon and Bert, along with Hubert and Loren, participated in round-ups and horse captures, sometimes working with the Park Service.

Bert kept meticulous records of his earnings and expenditures, both at home and on his job, and they offer a glimpse of the daily considerations of a ranch life.
