Storm Mountain quartzite flagstone

If you want a silver stone, Storm Mountain is worth a look. It is a quartzite from Idaho, light to dark gray with accents of golden brown veining. From a few steps back the overall effect is silver. Quartzite is harder than sandstone. Storm Mountain comes in patio and select flagstone, tumbled flagstone, veneer, ledge stone and boulders, which makes it easy to use across a whole yard.

Flagstone, tumbled, veneer and ledge

Patio flagstone lies flat in smaller pieces for walkways and small patios. Select gives larger coverage pieces. The tumbled form has rounded edges for coping and wall tops.

Veneer is thin cut for facing walls over concrete. Ledge stone builds walls, and boulders finish the look. Slabs are listed separately on the Storm Mountain Slabs page.

Planning with Storm Mountain

If you want flagstone, veneer and boulders to match, talk through the whole job at once. Large orders can deplete stock, and quarry access varies with weather.

Bring measurements and a photo of the house. Our flagstone calculator helps you estimate before your visit.

Winter can slow things down. Quarries sometimes lose access in heavy rain, so if you are planning a spring project, ask about timing early.
