The Norrlandic Slate Culture was a hunter-gatherer culture that emerged in northern Sweden during the transition from the late Mesolithic to the early Neolithic, c. 4200 BC. This paper deals with the Slate Culture’s relation to its neighbouring, contemporary cultures in Norway and Finland, and examines three types of typical finds related to the Slate Culture: enclosures of fire-cracked stones (Swe. skärvstensvall), petroglyphs and slate objects. The conclusion is that the Slate culture found inspiration to these phenomena from its neighbouring cultures and turned them into something of their own.

Boplatsvallar, often translated as semi-subterranean settlements, is an ancient monument with a diffuse definition. Defined as –embankments that partially or completely surround a often lowered/dug down surface- this category of ancient monuments is also made up of a former category which traditionally was interpreted as winter settlements from the late Stone age in Sweden. This view of the ancient monuments carried over, to a certain extent, to this new definition. Should this be the case, that this category of ancient monuments are remains of winter settlements,  used recurringly over an extended period of time, then they should exhibit similar signals in regards to the distribution of the anthropogenically altered soil chemical and soil physical properties at the sites.The area around Lillsjön, Anundsjö parish in Ångermanland, have four boplatsvallar located separately in the regional area. This means that they can be considered single contexts suitable to test the aforementioned hypothesis.The result of the intra-site study indicates that the sites have been used differently. Two of the sites exhibit a more local distribution of the heightened values of phosphates and magnetic susceptibility, distributed close around the ancient monument itself. The other two sites have a distribution of heightened values spread over a larger area around the ancient monuments, where one of the ancient monuments shows no particular difference from the background values at the site.This results thus suggests that there is a difference in how these boplatsvallar have been used prehistorically.

Pits and mounds in pebble: A study of archaeological remains in ancient pebble beaches inthe county of Västerbotten. Pits (Sw. boplatsgropar) and mounds (Sw. boplatsvallar) in ancient pebble beaches are two types of archaeological remains that are common under the highest coastline in the county of Västerbotten, Sweden. Although common, knowledge of these archaeological remains is limited. Organic materials left in pebble formations rapidly break down and degrade due to high exposure to moisture and weather, making dating by traditional archaeological methods such as 14C or dendrochronology impossible. The data for this study consists of two parts. One part has been collected through field surveys by the author and the other part is collected from National Heritage Board´s database of archaeological sites (Sw. Riksantikvarieämbetets kulturmiljöregister). The result of this study suggests that the majority of smaller pits and mounds in ancient pebble beaches have been used for storage and that larger pits and mounds are big enough to have functioned as foundations for simple dwellings. It also suggests there is some spatial coherence between the type of archaeological remains known as hut foundations (Sw.tomtningar) and pits in ancient pebble beaches. Albeit this coherence is slight and may be a coincidence. Furthermore, the study suggests there is a spatial coherence between quartz and quartzite handled by humans and pits in ancient pebble beaches that is not a coincidence. Suggestively, some pits in ancient pebble beaches that can be found today have been made and used in prehistoric times, by people who used quartz and quartzite in their daily lives.
