Let \Gamma be a singly degenerate closed surface group acting properly discontuously on hyperbolic 3-space, {\Bbb H}^3, such that {\Bbb H}^3/\Gamma has positive injectivity radius. It is known that the limit set is a dendrite of hausdorff dimension 2. We show that the cut-point set of the limit set has Hausdorff dimension strictly less than 2.
