Welcome!
I work with the geoarchaeology of old stone: quarries, monuments, rock art. And I try to figure out about their weathering, and conservation using traditional crafts. I also burn lime the traditional way. Many of my domestic services are managed through FABRICA, a registered Norwegian company established with good partners. On this website I publish articles on geology and cultural heritage. For the joy of old stone! Per Storemyr

The rhyolite quarries at Bømlo in Norway: Traces of firesetting in the Neolithic
A couple of days ago I climbed the mountain Siggjo in Western Norway together with my family. Siggjo is renowned for its deposits of the volcanic stone rhyolite that was heavily used for arrow heads and other tools from c. 4000 to 2500 BC in the Norwegian Neolithic. Finally I got to see the great traces of firesetting that are present in these hilltop quarries! The traces were interpreted by archaeologist Sigmund Alsaker almost 30 years ago, and we relied on them as an important reference when conducting experiments with firesetting in the North-Norwegian Mesolithic Melsvik chert quarries two years ago – experiments that I have previously reported in my blog.

Nidarosdomen og forvitring – sett fra 17 år tilbake i tid
Ganske tilfeldig kom jeg over en utgammel tekst om Nidarosdomen og forvitring her forleden. Det viste seg snart at det var en omtale av min egen doktoravhandling om temaet fra 1998; stødig ført i pennen av Hans Georg Jürgens og publisert i Universitetsavisa i Trondheim. Så leste jeg gjennom. Og fant ut at det meste har aktualitet den dag i dag. For om man googler “Nidarosdomen og forvitring”, så dukker det fortsatt opp helt tullete skremselsbilder om gigantisk luftforurensning som tærer på nasjonal-helligdommen. Nei, forvitringen på Nidarosdomen er nok mer kompleks enn som så.
Så jeg tillater meg å sitereden 17 år gamle omtalen til Hans Georg Jürgens i sin helhet. Den har tittelen:
“Nidarosdomen skranter… Continue reading

Steinhoggerne – hvem var de? En reise i tid og rom
Mange spør meg om hvem steinhoggerne var i gamle dager. Var de frie folk, var de treller, var de svært proffe? Eller hadde de et yrke som egentlig alle kunne utøve? Ikke lett å svare på! For bryting, hogging og … Continue reading
Geologi og kulturminner – bevaring av gamle steinbrudd
“Verdifull naturarv” – det var temaet på NGU-dagen 5-6 februar 2015. Det dreide seg om forvaltning, bruk og vern av Norges geologiske mangfold. Kulturminner og kulturlandskap er en selvfølgelig del av dette temaet og dermed også gamle steinbrudd. De viser på en sjeldent instruktiv måte menneskenes omgang med det geologiske mangfoldet. Men for å kunne formidles, må bruddene bevares! Dette var temaet for mitt foredrag på seminaret. Her kan du lese en lett redigert versjon av innlegget, med tilhørende powerpoint-bilder.

Happy New Year from Hyllestad! With a mountain and a fjord from summer to winter
With a cavalcade of 22 photos I wish you all a Happy New Year! And thanks a lot for following my blog in 2014! All the pictures have been taken from the balcony of our new home at Hyllestad in Western Norway. From August through the fall and into December. I cannot get enough of the stunning views of Åfjorden, the striking mountain Lihesten and the prominent hill Alden far out towards the sea. And of how the weather rapidly changes where fjords and mountains meet the Atlantic. A place to hopefully write many more blog posts in 2015… Continue reading
