Johannes (1915-2003) drev landbrug her. Han boede hele sit liv på Østermarken. Der har været mennesker her siden stenalderen, og tre af de utallige flintredskaber som Johannes har fundet i marken, ligger i cachen. Siden middelalderen boede menneskene i Nordby og kom kun på Østermarken for at passe jorden. Sidst i 1800-tallet flyttede man gårdene ned på markerne, og folk boede på den jord de drev. Nu godt 100 år senere er tendensen vendt: Landbruget drives igen af folk oppe fra Nordby, og der bor ikke længere landbrugere på selve Østermarken.
Cachen ligger inden for klitten i en granplantage som Johannes selv har plantet. Det ligger i sagens natur at plantagen er privat område, men vi har en klar aftale med ejeren om at geocachere må færdes i plantagen. Selve klitten er sikret mod sandflugt med roser som er sået af Johannes' far. Man bør ikke forsøge at bane sig vej fra stranden til plantagen gennem roserne; dels er det stort set umuligt, dels tager roserne skade.
På stranden har man udsigt til Hjelm, Vejrø, Kyholm og Hønsepold.
Johannes (1915-2003) worked the farm here. He lived all his life on Østermarken. People have lived here since the stone age, and the cache includes three of the numerous flint implements that Johannes found in the fields over the years. Since medieval times people lived in Nordby and only came down here to work the fields. In the late 19th century the farms were moved out from the village and people would live on their own land. Now a little more than 100 years later the tide has turned. The fields are once more worked by people from the village, and no farmers live on Østermarken any longer.
The cache is inside the dunes in a grove of fir trees that Johannes has planted himself. The area is private property, but we have a clear agreement with the owner that geocachers are allowed to come here. The dunes are covered with roses that were planted by Johannes's father. Do not try to make your way through the roses from the beach: It is virtually impossible, and you are likely to damage the roses.
From the beach the view spans the islands Hjelm, Vejrø, Kyholm, and Hønsepold.
