for which he became well known. As head of the sculpture department, he felt compelled to work in as many sculptural media as possible, evidenced by his solo exhibition of stone, bronze and welded steel sculptures at the Heard Museum in Phoenix, Arizona in 1970. The following year, Houser exhibited paintings and sculpture at the Philbrook Museum of Art in Tulsa, and in 1973 was awarded the Gold Medal in Sculpture at the Heard Museum Exhibition. Exhibitions, awards, and accolades continued. In 1975, he was asked to paint the official portrait of former U.S. Secretary of the Interior Stewart Udall. That same year, he had a solo exhibition at the Governor's Gallery at the State Capitol in Santa Fe. After thirteen years at IAIA, Houser retired from full-time teaching to devote himself to sculpture. Later work Houser's retirement in 1975 marked the beginning of the most prolific stage of his career. With time, materials, and the family compound in southern Santa Fe county, Houser honed the visual language that was to become his artistic legacy.

The piece honored both the memory of his parents, Sam and Blossom, and commemorates the 70th anniversary of the release of his tribe's prisoners-of-war from Fort Sill. Houser's work was explored in a series on American Indian artists for the Public Broadcasting System (PBS). Other artists in the series included R. C. Gorman, Helen Hardin, Charles Loloma, Joseph Lonewolf, and Fritz Scholder. In 1985, Houser's monumental bronze, Offering of the Sacred Pipe, was dedicated at the U.S. Mission to the United Nations in New York City. A year later, he made a bronze bust of Geronimo to commemorate the hundredth anniversary of the surrender of the Chiricahua Apaches. A cast of the bust was later presented to the National Portrait Gallery, where it remains in the permanent collection. In his last five years, Houser produced a remarkable number of pieces, and received many awards for his life's work. In 1989 he
