- For the 1998 field season, Jesse Byock and several students did a preliminary survey of the Helgafoss area in the near highlands, where clear remains of buildings can be seen.
- We tested phosphate techniques throughout the area and undertook an exploratory excavation on the northeast corner of the hay meadow (tún) at Hrísbrú.
- At the Hrísbrú site, the team unearthed small sections of well-defined walls from a medieval building within which were collapsed roof materials.
- These turf walls showed signs of the medieval tephra or ash layer (early thirteenth century). Radiocarbon dating of a small wood chip found in the turf walls produced a date of 650 ± 50 years and was inconclusive.
