Gravel Pit

Welcome to Frontier Stone Company! Frontier Stone is a family owned gravel business with years of experience with decorative and construction products. We are the largest supplier of decorative rock, moss rock and flagstone rock in Western South Dakota. Frontier Stone Company has its company headquarters in the Black Hills, near Rapid City, South Dakota.
At our Gillette, Wyoming quarry we mine a colorful rock known as Western Sunset. This is a lightweight stone which has multiple uses. It can be used for decorative as well as construction projects. We stock the decorative rock and the construction grade road gravel at both company locations.
Wyoming Red RockDecorative rock is a maintenance free solution for your landscaping needs. With one application you have installed a lasting accent color. The rock can be used as a border around buildings, trees or shrubs. Decorative rock is pet friendly and when properly installed, is plant resistant. Unlike wood products, it can be used on hillsides or drainage areas and remains in place against wind and rain. Decorative rock will not decay, it's fire resistant and quickly increases the value of your home. With all the sizes and colors to choose from we can satisfy any need you have!

Some of our most unique products are the boulders that are available from our Gillette quarry. These boulders are striking in color and texture. When the rock was created, heat forced the minerals to blend and flow together. These boulders look especially attractive when placed on a bed of our Western Sunset rock.


Our construction products include road gravel in the 2" and 1" minus sizes. We also can provide custom materials to fill our customers’ needs. Trucks can be loaded at our Gillette quarry or the Black Hawk headquarters. We provide the loading service and there are scales at both sites. We have a complete knowledge of the transportation options available to deliver our products at the lowest cost. Our company trucks offer regional delivery and we have access to the Burlington Northern Santa Fe Railroad for nationwide service. Contact us for a quote.
