  We study extremal surfaces in the Schwarzschild de Sitter spacetime with real
mass parameter. We find codim-2 timelike extremal surfaces stretching between
the future and past boundaries that pass through the vicinity of the
cosmological horizon in a certain limit. These are analogous to the surfaces in
arXiv:1711.01107 [hep-th]. We also find spacelike surfaces that never reach the
future/past boundaries but stretch indefinitely through the extended Penrose
diagram, passing through the vicinity of the cosmological and Schwarzschild
horizons in a certain limit. Further, these exhibit interesting structure for
de Sitter space (zero mass) as well as in the extremal, or Nariai, limit.
