Sidee bay ahayd markii San Francisco Bay la abuuray?
Context:Ilaa iyo xilligii barafka ee ugu dambeeyay, saxanka oo hadda ay ka buuxdo San Francisco Bay wuxuu ahaa doox weyn oo toosan oo leh buuro yaryar, oo la mid ah dooxyada ugu badan ee Xeebta Xeebta. Markay barafku sii dhalaalayeen, 11,000 oo sano kahor, heerka biyaha badda ayaa kor u kacay 5000 BC heerka badda ayaa kor u kacay 300 feet (90 m), oo ka buuxisay dooxada biyo ka yimid Badweynta Baasifigga. Dooxadii waxay noqotay xeeb, buuraleydii yaraydna waxay noqdeen jasiirado.
qiyaastii 11,000 oo sano kahor ayaa dhulku bilaabay in uu barafoobo laguna dhalaaliyo barafkii weynaa, taas oo kor u qaaday heerka biyaha badda islamarkaana buuxisay dooxadii ay hada ku taalo gacanka San Francisco
