By the late 2260s, Vigeland was a young woman.
In 2268, Vigeland joined Leonard McCoy and Gorshim Horst on a survey mission to an unnamed planet. The team discovered a city full of centuries-old sleeper units, most of which contained deceased humanoids. In one facility, however, she discovered one humanoid who was still alive. Vigeland and Horst were suddenly grabbed by a monitoring robot and placed into stasis chambers. McCoy discovered them and tried pulling her out of the unit, removing needles and giving her a stimulant, but then he himself was put into stasis and Vigeland returned to her unit.
A rescue team was able to revive McCoy and Vigeland, but Horst died. While in stasis, drugs injected into them appeared to produce great pain. (TOS - The New Voyages 2 short story: "Marginal Existence")
