The 39-year-old Megan Huntsman entered six guilty pleas Thursday morning in a court in Provo.
Huntsman will be sentenced April 20. She faces up to life in prison.
The agreement brings closure to a case that sent shockwaves through the quiet, mostly Mormon community where Huntsman stored the tiny bodies for more than a decade.
Her estranged husband found them in April 2014 in the small city of Pleasant Grove, Utah, south of Salt Lake City.
Authorities say a seventh baby found in her garage was stillborn.
The snowmobile trails opened in Vilas CountyFriday at 5 p.m.
