L. G. Everist, Inc. is your source for the most durable landscaping products on the market. Our landscape materials are made from Sioux Quartzite, one of the world's most beautiful and strongest stones. Quartzite in the Sioux Falls area is typically a dusty rose or mauve, but can vary in color from light pink to deep purple. Each stone has its own unique color and grain structure. Occasionally, perfectly formed "moons" appear on the stone. Legend has it that these moons are where spirits have touched the stone and left their mark, thus each piece has nature's own fingerprint.
