No county inventory for Perthshire was published by RCAHMS, however Kinross was published with Fife and Clackmannan (RCAHMS 1933). While the most areas of Perth and Kinross were studied through the Marginal Land Survey over 1956–58 (Geddes 2013), the imbalance between Kinross and Perthshire was only, in part, resolved through the significant surveys of north-east and south-east Perthshire (RCAHMS 1990; 1994). These documented well the field archaeology found north of the Tay estuary and east of the River Tay. However, there has been no large-scale, consistent survey across the rest of Perth and Kinross since. Occasional smaller-scale landscape studies have been carried out, such as at Menstrie glen, in part within historic Perthshire, in the Ochils (Cowley and Harrison 2001), below Ben Lawers (Atkinson 2016) and in lower Strathearn (Campbell and Driscoll 2020). This patchwork of survey has no doubt influenced thinking regarding the period and should be considered when research is being planned.
The distribution of known Pitcarmick-type buildings was dictated by the extent of RCAHMS (1990) survey. Since then, examples have been recognised west of the River Tay, including Strathbraan and near Kinloch Rannoch. It is possible they were once ubiquitous across the region’s inhabitable uplands, but further work is required to confirm examples outside the RCAHMS 1990 and 1994 study areas.
