Rimrock Mall is a shopping mall located in Billings, Montana. It is managed by Starwood Capital Group. Rimrock Mall is Montana's largest and most successful mall. A fast-growing tourist trade and the lack of a state sales tax further add to the sales success of the property. The center is one mile (1.6 km) from Interstate 90 in the rapidly growing sector of Billings on 24th Street West. The mall has a unique anchor history in that Dillard's has over time occupied 3 of 4 anchor locations (former Hennessey's, and now former Ward's and The Denver/J.C.Penney) while J.C.Penney has occupied 2 of 4 anchor locations (former The Denver, and now former Hennessey's/Dillard's).
