“…The drumlin ridge is part of the extensive Burtnieks Drumlin Field, which was formed by Weichselian glacier activity. Global warming at the start of the Holocene meant that glacier ice started melting and large bodies of water formed (Zelčs et al, 2011;Zelčs and Nartiss, 2014). Several smaller rivers flow into Lake Burtnieks, whereas only the Salaca river flows out of the lake.…”

This study discusses waste management by mid-Holocene hunter-gatherer-fisher communities at Riņņukalns, on the Salaca river in Latvia. It combines microscopic analyses with geochemistry and radiocarbon dating. We observe natural landscape changes and human responses, with Mesolithic and earlier Middle Neolithic occupation on the floodplain. During the later Middle Neolithic, we see a pattern of selective deposition of waste categories (food waste, combustion waste, and excrements) as part of collective waste management practices, led to the formation of a shell midden. Analysis of these waste layers provides an alternative perspective on subsistence practices and craft activities. A dump of ochre production waste illustrates the burning of iron rich sediments to obtain this pigment. These later Middle Neolithic hunter-gatherer-fisher communities had a collective approach to waste and waste management. The shell midden, which was also used for funerary rituals, can be regarded as a persistent and significant place in the landscape of these, perhaps not so mobile, communities.

In interstadial deposits, sand interbeds gain limited consideration in comparison with organic sediments, and therefore tend to be underrepresented in palaeoenvironmental reconstructions. The Raunis site, central-eastern Latvia, is an example where organic beds have already gained some attention and been used to understand the complex interactions between advance and retreat of the Scandinavian Ice Sheet in the region. Sandy interlayers have so far not been investigated in detail and their time of deposition has also been unknown, therefore exploring these clastic-organic sediment alternation is of interest. This study provides a new set of luminescence datings along with sedimentological information from the character of individual quartz grains as detected from scanning electron microscope (SEM) analysis. Sandy interlayers are dated to between 12 ka and 122 ka. Fast component OSL signal dominates in all investigated samples, but several samples have broad and/or skewed dose distributions. Only one sample is considered reliable and provides an age Authors' accepted manuscript (revised version after peer review, prior to journal layout and proofs) of 12.0±0.6 ka. A radiocarbon age from organic sediments in the same unit yields an age of 14,025±270 cal y BP. These two dates do not agree within 2 sigma, and this is likely related to reservoir and hard water effects of the radiocarbon sample. Sediments at the Raunis site fall into the Greenland Interstadial 1 (GI-1), but more detailed specification is not possible. The rest of the OSL ages are older than expected, likely due to incomplete bleaching during deposition. This means that stratigraphic reliability of this key site is likely hampered for further regional correlation.
