"This is dangerous," shouted Dafydd.

Roedd y rhew yn prynu ac yn llaesu o'u hamgylch.

The ice gathered and spread around them.

Ond roedd Gwyneth dewr, ac yn gwybod gwerth gwirionedd gwyddonol.

But Gwyneth was brave and understood the value of scientific truth.

Gwelai Gwyneth fod angen cynhaliaeth.

Real fears surfaced when the crevasse opened before them.
