Dettmer, John - Storm Cellar
May Day Township
This arched cave is built into a slightly raised mound to the north of a two story wood frame house. It is clearly completely underground. It's apparently a multipurpose structure. The cave is several dozen yards away from the house so this makes it an odd place to have built the cellar or storm shelter in terms of convenience. This cave as well as that of Swan Isaacson and Jacob Hay all seemed to have shared a similar style and size which would indicate the same mason as their builder. The cave opens to the south and measures 18'(L)x10'(W)x6.5'(H).
