An injured Manitoba woman who crawled up a snowbank to seek help after spending overnight in a frigid ditch trying to keep her young daughter warm has lost her feet to frostbite.

Kristen Hiebert and four-year-old Avery were going home last month when their car slid off a rural highway near a bridge and rolled down a steep slope to the frozen Souris River.

They spent the night huddled together for 10 hours as temperatures dipped to –23 C.

Her friend, Morgan Campbell, says Hiebert's feet had to be amputated last week.

Campbell says on a GoFundMe page that Hiebert's family is overwhelmed but buoyed by public support.
