Wallace Pratt, a Texas oil geologist working for Humble Oil Company, first discovered McKittrick Canyon in 1921 and fell in love with its natural beauty and geological significance. Over the years, he acquired extensive land rights to the canyon and built a stone cabin there as his summer retreat by 1932. In the early 1940s, after the death of his first wife, Pratt married Iris Calderhead and they constructed an innovative home known as "Ship on the Desert" outside the canyon in 1943. This unique building was designed to blend modernist architecture with the desert landscape and pay homage to Pratt's career in the oil industry.

Pratt → buy → Canyon
He called the property Manzanital Ranch.
