Rockglen Pastoral Charge was formed as a United Church charge sometime between 1926 and 1932, part of Assiniboia Presbytery and consisting of preaching points at Killdeer and Lacordaire (the latter was previously part of Pretty Valley Pastoral Charge, ca.1926). Between the late-1930s and 1940, the charge had amalgamated with Constance, as Rock Glen - Constance Pastoral Charge, with additional points at Lacordaire, Canopus and Killdeer (only Fife lake by 1946). By 1951, the charge had joined with Coronach to form Rock Glen - Coronach Pastoral Charge, with points at Rockglen, Coronach, Fife Lake, Hart and Clydesdale. The charges had separated again by 1958. As of 1962, Rockglen Pastoral Charge consisted of the Rockglen, Fife Lake and Killdeer congregations.
Around 1968/1969, Coronach combined with Rockglen Pastoral Charge (including Killdeer and Fife Lake) to create the new Borderlands Pastoral Charge.
