Industrial mineral site no. 1851, known as "Dry Creek Deposit" is a site in Chelan County, Washington. This site has been associated with limestone and marble. A notation found in DGER Bulletin 52 on page 398-403 says "Most of the limestone is white to light gray in color and fnely to coarsely crystalline in texture. However, some parts of it are composed of thin-bedded, finely crystalline white, gray, buff, and black layers that are highly contorted", and designates the value as "The composition is quite variable, and some parts of the limestone are high in magnesia".
