| Relative position | Occurrence is reported by Rose (1966) as being inside the Eklutna Tunnel (marked AQUEDUCT on map), 300 ft from the north end of the tunnel. The tunnel runs through East Twin Peak, connecting Eklutna Lake with the Eklutna Powerhouse (on south side of Old Glenn Highway). Location is accurate within a few tens of feet. Locality 44 of Cobb (1972) and locality 33 of MacKevett and Holloway (1977). |
