structures. Thereafter, excavation proceeded by hand, the spoil tipped in a trailer which<br />

was periodically emptied off site. After stripping, a 5m site grid was established on the<br />

same alignment as the national grid (Hjörsey), us ing 4 base points provided by Vegagerð<br />

ríkisins, who also set three fixed station points around the site. For our internal site grid<br />

however, we used an independent, arbitrary numbering system, employing eastings and<br />

northings as the national grid points worked on a westings and northings system. The<br />

conversion is given below for two points:<br />

Excavation methodology employed a modified version of single-context/unit recording<br />

developed by Fornleifastofnun Íslands with a strategic sampling programme for<br />

environmental remains. Numbers in square brackets (e.g. [001]) in the text in this report<br />

refer to this unit index system. The main innovations to the recording system used at<br />

Skálholt were twofold: the first involved a single A3 permatrace record sheet with<br />

combined plan (5x5m square at 1:20) and unit description along one side. This decreased<br />

paperwork, made a separate graphics register redundant, and generally accelerated the<br />

recording process. The second change involved conceptual changes to the unit index – a<br />

two-level system was implemented with unit numbers either referring to discrete<br />

depositional/stratigraphic contexts as before (cuts or deposits) or amalgamations of such<br />

units (at any level of generalization, labeled as groups). As a supplement to the primary<br />

A3 record sheet, an A4 group sheet was employed for detailed discussion of such groups.<br />

The group context type was advantageous insofar as it encouraged greater scope for onsite<br />

interpretive recording and, in that it permits multiple hierarchies of grouping, it is<br />

infinitely flexible. In the unit register it was also decided to include our own and<br />

previous excavators actions, being also part of the history of the site; thus archaeological<br />

trenches/cuts and spoil/backfill were entered in the same index. Otherwise, all aspects of<br />

the system remained as used on other FSÍ sites – a photo register, sample register and<br />
