His family moved to Colorado when Sylvanus was ten years old, and his secondary education was completed at Buena Vista and Colorado Springs. It was during his later schooling in Colorado that Morley first developed an interest in archaeology, and in particular Egyptology. However his father—a man trained in the hard sciences and who had graduated at the top of his class in civil engineering at PMC—was initially unsupportive of his ambitions. Seeing little scope for employment opportunities in archaeology, the Colonel encouraged his son to study engineering instead. Sylvanus duly enrolled in a civil engineering degree at PMC, graduating in 1904.
