Excerpt from Geology and Ore Deposits of the Republic Mining District Ou the east side of the Cascade mountains three sites were selected as follows: At Selah Gap, two miles north of North Yakima, in Yakima county; at Marshall, a few miles southwest of Spokane, in Spokane county; and at Dixie, 11 miles north east of Walla Walla, in Walla Walla county. At all of these places basalt of good quality occurs in sufficient quantities to supply large crushing plants for a great many years. In each instance a railway line passes directly by the quarry, thus making the shipping problem an easy one.
