A secondary valley in the Shigar River Valley, 15 km NW of Shigar. Excellent specimens have been found in nearby alpine cleft-type deposits.

Notes:
- The locality name is sometimes misspelt "Aschudi".
- Finds of triplite and väyrynenite have been erroneously attributed to this locality (Blauwet, 2006); the triplite actually was found at the Namlook mine near Dassu, while the väyrynenite may come from several different localities (e.g., Nyet).
