We report a linear age gradient found in the W48A star formation region from age dating based on luminosity-mass diagram together with submm-radio molecular line and continuum data. Also the surroundings of W48A show evidence of an evolutionary gradient suggesting that a large-scale external force, probably the Aquila Supershel, influenced the entire W48 region.
