It was then a thickly forested area with tall and big trees interconnected with myriads of rattan vines called barit.

As a consequence flash flood occurred that resulted to siltation in the deep river bed portion virtually neutralized the hiding place of these buayas.

The first formal collective name of the municipality of Luba was Barit-Amtuagan, presumably to include all other settlers from the east side of the kayan (river).

But in 1920, Caoatig Valera, the third presidente of the municipality of Luba transferred the town capital to Bancagan (now Poblacion) in answer to the clamor of some influential people in that sitio.

The town's geographical location has been a major factor in her slow-paced development that she is often tagged as a marginalized community of Abra.

It is bounded on the north by the municipality of Manabo; north-east by Boliney; east by Tubo; south by San Emilio, and west by Villaviciosa.
