The Great Sand Sea in Egypt presents the history of one of the large sand seas in the Sahara, beginning with the sand supply by fluvial transport from partly distant areas and also by local sandstone weathering. It also details sand as carrier of information and shows the possibilities of sedimentary analysis in dealing with such a topic. Simple measurements may supply important information (e.g. salinity measurements). Well known methods can be developed further to answer special questions. A wealth of information can be drawn from especially adapted sedimentological investigations. In the end, bits of information from different analytical sources can be put together to reveal the history of a large sand sea. *Analyzes different geological sources to decipher the history of the Great Sand Sea *Presents the possibilities of sedimentary analysis to interpret the history of an area *Develops well-known methods to further answer special questions

This volume presents the results of a long study begun in 2004 within the framework of the Archaeological Mission in the Farafra Oasis of Egypt directed by Barbara Barich and Giulio Lucarini, of the Sapienza University of Rome (now under the auspices of ISMEO). The book focuses on the features known as “Steinplatz-type hearths” and their role in the settlement patterns of the human groups living in the Egyptian Western Desert during the middle and late Holocene. Steinplätze are concentrations of burned and fire-cracked stones that vary in shape and size, and have often been slightly elevated above the present ground level by post-depositional erosion processes. Occurring both as isolated features and in clusters, they are often the only visible structures – or even traces – of ancient settlements. The study of these features is closely interconnected with the mobility strategies of the communities that inhabited this desert region during a period of higher average rainfall than at present but also characterised by significant climate fluctuations, with humid periods interrupted by dry spells and eventually ending in an overall trend towards greater desertification. The use of the Steinplatz-type hearths was most widespread in the second half of the sixth millennium BC, when mobile occupation strategies replaced a more sedentary model. An analysis of the Farafra Oasis Steinplätze is coupled with a general reassessment of the subsistence and mobility models hitherto proposed for the Eastern Sahara, suggesting an integrated occupation system for Farafra itself. The economy of the forager-herders of the middle Holocene, during the climate optimum (6900-5550 cal BC), seems to have relied significantly on herding small livestock, but also on hunting, and likely concentrated on the gathering of wild cereals such as sorghum. During the climate optimum, forms of seasonal stabilisation of the settlement strategy seem to emerge, with the alternating occupation of two different winter and summer villages consisting of clusters of stone-slab huts; short-term task-specific camps, using Steinplätze, logistically completed the system. After this phase, only short-term camps with Steinplätze were occupied. These were probably directly dependent on the wettest areas at the centre of the oases and made use of a tethered exploitation strategy, with brief movements from the central oasis (“daisy-chain” movements). The use strategies of the Steinplatz-type hearths within the mobile settlement system are outlined adopting a clear and immediately assessable model. “Yet although they are among the most distinctive of the Sahara’s archaeological features, Steinplätze have received little systematic attention in recent decades. Marina Gallinaro’s work thus marks a new phase in their study, one that draws them back into discussions of how early livestock-keeping populations in Northeast Africa used the resources and landscapes to the west of the Nile along a trajectory of increasing aridification that eventually culminated in the desert we see today (…) Lucidly written, Gallinaro’s volume will, I believe, help inspire individuals to take up the research agenda she sets out. At a time when so much of the Sahara is off-limits to archaeological fieldwork, it is deeply gratifying to see here yet more evidence of the thoroughness and high quality that have characterized the work of Italian archaeologists in this region of Africa over many decades. The continuing publication of their research, Marina Gallinaro’s included, in the Arid Zone Archaeology monograph series will surely help sustain widespread interest in Saharan archaeology until it becomes possible to excavate and survey again free of current geopolitical restrictions. May that day come soon!” Prof. Peter Mitchell, University of Oxford, UK.

Oceans were long thought to exist in all corners of the Solar System, from carbonated seas percolating beneath the clouds of Venus to features on the Moon's surface given names such as "the Bay of Rainbows” and the "Ocean of Storms." With the advent of modern telescopes and spacecraft exploration these ancient concepts of planetary seas have, for the most part, evaporated. But they have been replaced by the reality of something even more exotic. For example, although it is still uncertain whether Mars ever had actual oceans, it now seems that a web of waterways did indeed at one time spread across its surface. The "water" in many places in our Solar System is a poisoned brew mixed with ammonia or methane. Even that found on Jupiter's watery satellite Europa is believed similar to battery acid. Beyond the Galilean satellites may lie even more "alien oceans." Saturn's planet-sized moon Titan seems to be subject to methane or ethane rainfall. This creates methane pools that, in turn, become vast lakes and, perhaps, seasonal oceans. Titan has other seas in a sense, as large shifting areas of sand covering vast plains have been discovered. Mars also has these sand seas, and Venus may as well, along with oceans of frozen lava. Do super-chilled concoctions of ammonia, liquid nitrogen, and water percolate beneath the surfaces of Enceladus and Triton? For now we can only guess at the possibilities. 'Alien Seas' serves up part history, part current research, and part theory as it offers a rich buffet of "seas" on other worlds. It is organized by location and by the material of which various oceans consist, with guest authors penning specific chapters. Each chapter features new original art depicting alien seas, as well as the latest ground-based and spacecraft images. Original diagrams presents details of planetary oceans and related processes.

Kuno Gross: Most probably the readers of this magazine have never heard of the original TRACKS. I was in the very same situation until by the end of 2020, when NZ LRDG-historian Brendan OCarroll has provided me with a hardly readable copy of the June 1941 issue of TRACKS. I was immediately fascinated by these windows into the past and just thought: "We should revive TRACKS! " The editor of the original Tracks was, that time 20 years old, TA Sgt. N.A Moore, a clerk attached to LRDG Group HQ. The June 1941 issue was created by him when the LRDG HQ was located at Kufra. There he got the idea to create a "house paper" for the unit. He recalled in a letter which was published in the 1991 Newsletter of the LRDG Association, that there were only a very limited number of people who were willing to contribute and that this first edition was mainly launched thanks to the contribution of Lieut. Col. Bagnold and Captain Kennedy Shaw. And indeed, the June 1941 remained the single and only issue of Tracks - it was never published again.... until today!

Deserts are parts of the Earth that receive little or no rain; 25 cm or less per year. The physical processes that act upon these parched lands are vastly different from those that shape the more humid parts of the terrestrial landmasses. In the desert, wind is a major agent of erosion and transportation. As the results of recent space missions have indicated, this is also true in the case of the planet Mars. Thus, our understanding of desert processes sheds light on fundamental planetary processes that may apply on any planetary body that is enveloped by a windy atmosphere. An understanding of the physical layout of arid lands, and the nature of processes that initiate changes therein is also fundamental to thoughtful utilization of these lands for the benefit of mankind. It is with this in mind that we prepared this book for publication. We believe that the collection of articles in this book will be useful to scientists who are interested in desert landforms and processes, and to planners of economic develop ment of arid lands. The book also serves as a guide for students as to the state of our knowledge in this field as well as to the topics that require additional research.
