Landås 5 (Landåstunnelen I), Landås, Iveland, Agder, Norge
A feldspar quarry in a granite pegmatite dike located about 500m E of the Landås farm.
Bjørlykke locality nr. 45.
Barth (1931) calls this quarry "Landås I" (not to be confused with Landås 1 Feldspar Quarry).
Bjørlykke's 500m is clearly wrong since that would be a place east of the lake.
On his map, he places both Landås 5 and 6 below the right end of the lake, at a distance greater than 1 km from the farm.
An updated altitude map (2017) has made it possible to identify both Landås 5 and 6 with great certainty.
The structures visible on the map are convincing enough.
The locality in the east shows all signs of being a tunnel open on both sides and being 25 m long.
The coordinates are given for the entrance at the north side.
