Soil erosion poses a considerable threat to ecosystem services around the world. Among these, it is extremely problematic for archaeological sites, particularly in arable landscapes where accelerated soil degradation has been widely observed. Conversely, some archaeological deposits may obtain a certain level of protection when they are covered by eroded material, thereby lessening the impacts of phenomena such as plow damage or bioturbation. As a result, detailed knowledge of the extent of colluvial deposition is of great value to site management and the development of appropriate methodological strategies. This is particularly true of battlefield sites, where the integrity of artifacts in the topsoil is of great importance and conventional metal detection (with its shallow depth of exploration) is relied upon as the primary method of investigation. Using the Napoleonic battlefield of Waterloo in Belgium as a case study, this paper explores how different noninvasive datasets can be combined with ancillary data and a limited sampling scheme to map colluvial deposits in high resolution and at a large scale. Combining remote sensing, geophysical, and invasive sampling datasets that target related phenomena across spatial scales allows for overcoming some of their respective limitations and derives a better understanding of the extent of colluvial deposition.

Fumane Cave contains a sequence of natural and anthropogenic deposits documenting key transitions in the Paleolithic of Northern Italy. Open questions remain concerning the stratigraphic integrity, the formation processes, postdepositional alterations, and paleoclimatic implications of the sedimentary record. We examine these aspects through an extensive investigation based on field descriptions and micromorphological analysis of thin sections sampled during the last 25 years of excavations. Major components of the sediments are carbonate sands and limestone rubble originating from the physical breakdown of the cave roof and walls. Limited amounts of mica and quartz grains attest to weak eolian inputs. Sediments contain anthropogenic features and variable amounts of charcoal, bone, and lithic artifacts reflecting different uses of the site. Cryoturbation features observed in the field suggest an increased intensity of frost mainly after the accumulation of unit A2. This unit as well as unit A6 also show increased abundance of silt and clay cappings under the microscope, probably reflecting higher rates of snowfall and percolating meltwater during colder periods of the Last Glacial. However, limited expression of micromorphological features related to frost suggests rather modest changes in climate during the accumulation of the sequence. Overall, field descriptions and the micromorphological approach mostly corroborate the stratigraphic integrity of the sequence, underlining the high value of Fumane Cave as an archive of the late Middle to early Upper Paleolithic in Southern Europe.

This paper presents a unique set of maps and geospatial data covering 16 ancient terrace agricultural systems in the upper part of the Río Grande de Nasca drainage. These systems are located on the western Andean flank (1200 and 3800 m asl), in the districts of Llauta, Laramate, and Ocaña in Lucanas province, Ayacucho region, southern Peru (14.5° S). Spanning various periods of the prehispanic era (1000 bce–1532 ce), only limited sections of these terraces are still in use today. Our field methods include archaeological, geomorphological, and drone surveys. The terrace systems were mapped using (1) satellite imagery and (2) high-resolution Digital Surface Models (DSMs) within a Geographic Information System (GIS). The geospatial analysis and mapping results encompass parameters such as elevation range, terrace area, number and condition of terrace walls, length and height of terrace walls, area of individual terraced fields, associated architecture (e.g., irrigation canals), slope, current vegetation and use, and chronology. By documenting the widespread distribution, extent, and diversity of agricultural terraces in the region, this data set is extremely valuable for understanding prehispanic human-environment interactions and land use dynamics, as well as indigenous agricultural practices and resilience strategies in response to environmental and climate change.
本文介绍了一套独特的地图和地理空间数据,涵盖了Río Grande de Nasca流域上部的16个古代梯田农业系统。这些梯田系统位于安第斯山脉西侧(海拔1200米和3800米),位于秘鲁南部阿亚库乔地区卢卡纳斯省的Llauta, Laramate和Ocaña地区(14.5°S)。这些梯田跨越了前西班牙时代(公元前1000年至公元前1532年)的各个时期,只有有限的部分今天仍在使用。我们的实地调查方法包括考古、地貌学和无人机调查。利用(1)卫星图像和(2)地理信息系统(GIS)中的高分辨率数字地表模型(DSMs)绘制了阶地系统。地理空间分析和制图结果包括诸如海拔范围、梯田面积、梯田墙的数量和状况、梯田墙的长度和高度、单个梯田的面积、相关建筑(如灌溉渠)、坡度、当前植被和使用以及年代等参数。通过记录该地区农业梯田的广泛分布、范围和多样性,该数据集对于了解前西班牙人与环境的相互作用和土地利用动态,以及土著农业实践和应对环境和气候变化的复原力策略非常有价值。
