Þakkir
Ég vil þakka Arnþóri Garðarssyni alla rannsóknasamvinnuna í Laxá og
á Mývatni undanfarin 34 ár og fyrir að kynna mér rannsóknarmöguleik-
ana í Laxá árið 1976. Árni Einarsson, Haraldur Rafn Ingvason og Jón S.
Ólafsson lásu yfir handritið og færðu margt til betri vegar. Kann ég þeim
bestu þakkir fyrir.
