For three decades, Hamilton traveled throughout India, Pakistan, the former kingdom of Sikkim (annexed by India in 1975) and Japan. In Pakistan in 1959, she was asked to produce work for an exhibition that was administered by the foreign minister of Pakistan. The ministries of Pakistan also gave her permission to make her first K2 expedition. This expedition resulted in the welcome realization of her individual artistic vision and the creation of her first completely abstract work, "Burst Beyond the Image".
