| Ca. 15 m øst for stien som går mellom bebeyggelsen på vest- og østsida av øya. Rustbrunfarget flog (5x8 m) med mindre sprengningsarbeid. Ikke massiv magnetitt-malm, disseminert mt i plagioklas- og dels epidot- og granat- førende skarnliknende bergart. Sammenhengen til sidebergarten vanskelig å bestemme. Granitten kutter gneissen. |
