Sida laga soo xigtay Statistical Abstract of Ethiopia for 1967/68, haradu waxay dhererkeedu yahay 17 kiiloomitir ballaceeduna waa 15 km, iyadoo leh baaxad dusha sare ah oo isku wareeggeedu yahay 205 kiiloomitir oo laba jibaaran. Waxay leedahay moolka ugu sarreeya oo ah 14 mitir, waxayna ku taal joog dhan 1,573 mitir.
Dhinaca koonka waqooyi-bari ee haradan waxaa ku yaal dhowr ilood oo biyo kulul ah, kuwaas oo muhiim u ah dalxiiska iyo dadka deegaankaba.
Intaa waxaa dheer, waxaa jira hawlo laga qabto xeebta haradan oo laga soo saaro dambaska soodhada (soda ash), kaas oo soo saara 20,000 oo tan oo sodium carbonate ah. Kaydka la xaqiijiyay ee Harada Abijata, iyo sidoo kale harooyinka deriska la ah ee Shala iyo Chitu, ayaa ka badan 460 milyan oo tan.[1] Shimbiraha Flamingoes ayaa sidoo kale laga helaa harada.
Daraasado dhinacyo badan leh, oo ay ku jiraan baaritaanka sedimentology, palynology, diatoms iyo maaddooyinka dabiiciga ah ayaa lagu sameeyay muunad carco ah oo dhererkeedu yahay 6 m oo laga soo qaatay Harada Abijata, Itoobiya. Salka muunaddan waxaa la ogaaday inuu jiro 1720 ± BP. Falanqayntu waxay muujisay afar marxaladood oo kala duwan oo ku saabsan isbeddelka harada. Laba marxaladood oo xad-gudub ah (transgressive phases) oo la aqoonsaday ayaa lala xiriirin karaa caddaymaha kale ee heerka harada. Xad-gudubyadani waxay ka dhasheen isbeddelka agabka ka yimaada gobollada dhulka hoose iyo kuwa sare ee ku dhex jira dhulka biyaha qaada. Waxay u dhowdahay inay la xiriiraan isbeddellada hababka roobabka xilliyeedka.[2]
