McGregor Lake

Perched high, in the forest of Northwestern Montana, the McGregor Lake quarry overlooks its namesake. McGregor Lake is a prized variety of the popular Chief Cliff argillite. Quarried from a cliff formation, the stone from this quarry is visually stunning; predominately light gray in color, with strong gold bronze and tan tones. The dendrite fern patterning creates the striking look of natural, individual artwork. With the warmth of a Big Sky Country sunset and naturally recta-lineal shaping, McGregor Lake is unparalleled in versatility.

Moose Mountain

The newest quarry to the Montana Rockworks family, stone from the Moose Mountain quarry elicits constant compliments. The colors are grounded in a dark, smoky gray, with rich reds, dark chocolate brown and tans that blend together for a remarkable material. Because the stone is quarried from a talus formation, a dark patina is prevalent. Stone from Moose Mountain marries the colors from the nearby Castle Rock and McGregor Lake quarries, which make it an excellent choice to blend with our most popular Chief Cliff stones. The inspiration of this Montana, mountain ridge quarry, can be seen in every stone.

Castle Rock

With birds-eye views of two different valleys, Castle Rock is a high alpine quarry perched on a ridgeline. The core of the stone is dark gray, with surface coloring ranging from light tan to dark chocolate brown with occasional dark lichen. Castle Rock is hand and machine picked from talus slopes; the dark, common, patina is from centuries of exposure to the elements. When "Chief Cliff" is mentioned, most visualize the dramatic coloring found in this quarry.

Elk Mountain

The vast prairies of central Montana yield sought after sandstone...prized for its feel and coloring. Elk Mountain is a fieldstone quarry that produces a tactile, soft stone revered for its neutral color, with a preponderance of tan and subtle sage green. Stone from Elk Mountain is naturally flat and rectangular and historically, has produced remarkable, large slabs.
