The original chapter comprised the entire area of A-tsa Lodge and Grayback Council, principally the cities of Redlands and Yucaipa.
In 1992, the A-tsa Chapter absorbed the Morongo Chapter in the Pass area, adding communities like Beaumont and Banning to their area.
In 2010, when Cahuilla Lodge consolidated to their current chapters, A-tsa took in the greater area of San Bernardino that had previously been part of the Wisumahi Chapter.
