Site Name: NABESNA MINE
This is the end of the state maintained Nabesna Road. From here on, the road is privately maintained for access by four-wheel drive vehicles to the privately owned Nabesna Mine. Obtain permission from the mine owner prior to visiting private property. About 1/3 mile further, there is a gravel parking area. This is the best place to park your car. Approximately 1/3 mile past the parking area, a trail leads south towards the remains of the abandoned Rambler Mine, an area that was active after WWII, but never patented, and now part of the park. The trail is steep, but the effort rewards you with superlative views of the Nabesna River and Nutzotin Mountains.
The Nabesna Mine went into production in the early 1930′s and had produced over $1,870,000 in gold by the time that large scale mining ceased in 1940. Limited, small scale mining has continued since then. The mine entrance is on a very steep slope high up on White Mountain, so ore had to be transported hundreds of feet by aerial tramway down to the processing plant at the base of the mountain. The primary ore materials are gold-bearing pyrite and chalcopyrite which occur in limestone along with other metallic minerals such as magnetite, pyrrhotite, and pyrite. These mineral deposits probably formed when metal and quartz-rich fluids migrated from an underground chamber of molten material into nearby limestone where they cooled and solidified. Miles
This site case (2350) or EPA ID: AK0000333021 was opened in 1994 by State of Alaska Department of Environmental Conservation. The mine site is currently active; Wrangell-St Elias National Park is currently evaluating engineering cost analysis for site remediation. As of July 2012

Site Name: Old Copper Valley School Site
Site Information: The Catholic Church operated a mission boarding school in Tazlina for 15 years from 1956 until 1971. Alumni of the former Copper Valley School continue to hold annual gatherings in memory of their years at the school, which turned out many leaders in the Alaska Native community. In 1976, a fire destroyed the main buildings, and over the years the remaining outbuildings have deteriorated. Private housing has developed around the former school, which has become a common play area for the children who live in the area. Since 2010 there has been new energy from community members formed around this site. That has reestablished old partnerships and formed new ones, to find a way to restore this site to a safe and healthy part of the Tazlina community. These partnerships have hosted a number of community outreach and project awareness events in Tazlina to gain historic knowledge of site and perspective for future reuse of this property. Although this property is owned by the Catholic Church, Diocese of Anchorage, the Native Village of Tazlina, and many partners in conjunction with the Copper Valley School Alumni Association, would like to reuse this property for educational opportunities for the future Native leaders of Alaska. The community, which sees this site as a positive part of local history, would like to see the property used for outdoor education and environmental and subsistence activities for the general public.
