Its flow originates from the exposed sandstone outcrop located high above the Hubbard Creek Canyon along the eastern facing walls of the cliffs between the valley created by the North Fork of the Gunnison and Freemand Gulch. Site was inaccessible due to a slide Baseline information for Point S2-8 is derived from events beginning on 6/10/98 through 9/24/99. Point influenced by mining on 9/24/99. • Figure No. 43
