Location and accuracy This tunnel is at an elevation of approximately 1,300 feet on the south side of Gold Creek. It is 1.5 miles north of Roberts Peak and 1.5 miles west-northwest of Clark Peak in the NE1/4NW1/4 section 20, T. 41 S., R. 68 E. of the Copper River Meridian. The location is accurate. This tunnel is part of the Alaska-Juneau Mine and is included because it is marked by a symbol on the Juneau B-1 topographic map.

Geologic setting

Geologic description

This tunnel is part of the Alaska-Juneau mine (JU165) and the Perseverance mine (JU168); it is a crosscut driven in 1902 to access ore below the Perseverance mine. The Alexander crosscut was over 2,500 feet long by 1905. Until the Sheep Creek Tunnel and other workings were rehabilitated in the late-1980s, the Alexander crosscut was the best underground access to the Perseverance and Alaska Juneau mine (JU165) workings (Redman and others, 1985). This tunnel is part of the Alaska-Juneau Mine and is included because it is marked by a symbol on the Juneau B-1 topographic map.
