Let g be an affine Lie algebra with index set I = {0, 1, 2,…,n}. It is conjectured that for each Dynkin node k∈I\{0} the affine Lie algebra g has a positive geometric crystal. In this paper, we construct a positive geometric crystal for the affine Lie algebra D7(1) corresponding to the Dynkin spin node k=7.
