Between 1930 and 1940, approximately 18,000 tons of ore were mined from a low grade copper deposit (Stotelmeyer and others, 1982). DGER personnel vis- ited the site on July 12, 2001. Workings observed consisted of the open 11,000- foot Trinity tunnel adit, the caved St. Francis adit located 2.5 miles up Phelps Creek, and an open unnamed newer adit. The openings have locked but ineffec- tive doors. Both open adits discharge water into Phelps Creek. Previous work by the USFS raised concerns about ele- vated zinc levels in Phelps Creek. One Figure 2. Trinity townsite circa 1937. Concentrating mill in center; powerhouse in background on sample of the Trinity tunnel discharge right; saw mill in foreground. Only the powerhouse remains today. View to the north. analyzed at nearly ten times the WAC 173-201A chronic water quality standard for zinc (Table 5). Waste rock from all openings totals approximately 30,000 cubic yards of mostly unmin- eralized shot rock. Waste rock in the St. Francis area is eroding into Phelps Creek. Little remains of the 350-ton flotation mill at the Trinity townsite. No tailings were identified during this visit. SETTING The Royal Development Company op- erated the Red Mountain mine on the southern end of Phelps Ridge in the Entiat Mountains. Phelps Ridge is the south-southeast–trending shoulder of Red Mountain that divides Phelps Creek from the Chiwawa River. The site is approximately 42 miles north of Leavenworth. The privately owned townsite of Trinity includes the mill site and camp. It lies at 2800 feet elevation at the end of the Chiwawa River Road, near
