 The paper I am about to present regards the project material traces of pre-historical human activity in Campinas Forest carried out by State Ecological Museum in Warsaw. The project is developed on the base of cooperation agreement signed on 4 July 2017 between Campinas National Park and State Ecological Museum in Warsaw. Its main objective is the archeological server of Campinas National Park grounds based on possibility of wide query using state of art technologies but most of archeological site verification. Matagals, or at least part of them collected from the sites in Campinas National Forest, are starting the State Ecological Museum will be elaborated as well. In the future there is a plan to elaborate on the object collected in the Museum of Mazawian Ancient metallurgy in Pruszków. Campinas National Park is situated in center of Poland and practically borrows Warsaw acclimation to the north. It is located on central Mazawian lowland between the left bank of Wistula river and Zera river. The park covers over 38,000 hectares. The area of the Campinas National Park includes the Campinas Forest. Campinas National Park is one of the major Polish lowland farm sanctuary. It is estimated that the park is a natural habitat of half mainly of 16,500 native animal species. The biggest among the 50 mammals species is the most which is also a symbol of Campinas National Park. This animal were hunted to extinction in the middle of 19th century to be later reintroduced in the forest in 1951. Today their population totals 300 individuals. The most valuable park areas are under strict protection in the 22 protection zone. The biggest area of Zeraków is over 1,200 hectares. It is located just a few kilometers away from the Warsaw border. Campinas National Park was later founded on 16 January 1959 due to natural values and social importance in the year of 2000. Campinas National Park totals the protection zone was recognized by UNESCO as World Biospherical Reserve called Campinas Forest. The forest forms are clearly distinctive in the natural system. The forest territory compared to neighboring plains areas is characteristic for its big morphological variety. Moving from the north to the south there are current Vistula riverbed and interflute bank area which is marked with red color. Vistula flute plains, northern dune zone, northern pitbox zone, southern dune zone, southern pitbox zone, and ice and marginal valley bank and Wojcko-Pońska plains to the west and Warsaw plains to the east. The highest point is situated near Opalen next to Eastern Park border and it has 106 meters above sea level. The lowest is located in the western part of the northern pitbox zone which is 68 meters above sea level. The differences in relative height between dunes, summit and almost flat pitbox zones amount to 30 meters. Having made this introduction I would like to bring forward to the project guidelines. Its main objective is to carry out archeological server on Campinas National Forest based on possibility white quarry using state of art technologies. First stage of the survey is field verification of archeological sites located in Campinas National Park, grounds and registered in state archeological museum. Objects from these sites were collected during survey done in interwar period or they were finds reported in post-war period. Very often the location of these sites is limited to a very general description which makes it very inaccurate. The aim of our work is to locate sites known from the archives. Further state would be analysis archives collected from research of other centers and museums. Since 1978 a research program called archeological register of Poland systematical field working has been implemented in Poland. The survey of this area was carried out by Stefan Wojda team discovered in mid 80s of 20th century. Discovering a few hundred sites from different periods. Objects found in these sites joined the collection of the museum of Mazovian ancient metallurgy in Kruszkow. At the point only open land habitats filter meadows were explored while forests were ignored. This was due to methodology guidelines of the project. A part of the discovered sites is now covered by forest. An important query supplement is the LiDAR data analysis. We use already made visualization made for two big projects. Country protection against extreme hazards called ESOC and Campinas wetlands. They are planning to recalculate the clouds of points for our project especially areas not included in Campinas wetlands project. With these tools we do not only want to find characteristic feature but also predict places which might have been attractive for settlements of perfectly historical communities. The very important part of project especially for us museum professionals is science popularization. This is full fight during the number of excursion guided by archaeologists and a research worker from the park. The theme of each trip refers to a different historical period or in some cases to historical monuments remaining in a narrative around historical parks and places. Emphasizing and showing the relation between nature and human activities is particularly important. As well as showing changes in Campinas forest natural landscape over the years. Both natural changes and those influenced by human activities. As the next part of my report I shall present field work process in few cases. The field work last for one year and was focused on the unisones and their surroundings mainly in eastern part of Campinas forest. The first group of sites to be precisely located during the surveys known from archives or museum collections. Case one is Łóża d'Una. It is a group of sites located around Łóża d'Una. In state archaeological museum archives in Łomianki folder there is a private letter signed by letter escape probably Stefan Krukowski. Mark with date 13 January 1944 and closing sketch in the moment here is the plan of Łóża near Łomianki site. In state archaeological museum there is no data concerning flint material mainly outers interest. But there is free flint collections registered as Dąbrówka. But the time period between letters and the sites discovery is 19 years. So there is no certainly whatever this that was the same same sites. On the other hand highly improbable that such field work was carried out in 1944. Today Łóża d'Una is completely wooded and ground observation can be done only on small rooted fragments. Despite of few attempts over the time no material was find. And here we have the sketch which I was talking about. Here we have archive maps. Here we have matched the names of these villages which is on the sketch. We have to north is as you see on the other part of the sketch. And here is probably places which we were talking about in this letter. Case two is another dune. It's called Góra Ojca and in state archaeological museum collection there is published. There is set of one hundred and seven flints object named from the name of Laskiewicz. The site register card says Góra Ojca dune 1955 a gift from a doctor from Laskiewicz. However there's some additional information which I found during this study this collection on the labels. And first one say Laskiewicz district Góra Ojca dune behind the institution for visually impaired site two. So I thought that is where is site one in this cases. So I find the second label on the same box of object that changed our view of the analysed set. Laskiewicz district dune near a bus stop institution for visually impressed site one. Okay so I knew there is another site. We have here only one bus stop and this time when this collection come to museum. So we know there is not one site but two sites. So ultimately I try many times go on Góra Ojca dune and another dune near the bus stop. No of flint artefacts was found. And another case is biggest flint collection from Campinas Forest from Grohala. And it consists almost two thousand flint objects. It's collection dating back to final parallelity. Unfortunately based on archive data it is not possible to locate the site precisely. The only thing we are able to do based on labour description is discrepancy relation between particular clusters. In addition there is some value information on the relation between the site and the unspecified dune or wetlands. The survey gives a great news for complex study of highly interesting flint artefacts. The next project objective is verified sites known from the previous archaeological survey located in Campinas National Park. A great number of sites registered in mid-80s century were situated on fields or meadows. As a result of land acquisition policy of the park followed by afforestation of acquired areas. Today large number of these sites are covered by forest of mixed age. I want to present two examples of our field verification. First case is Cherakov. An example might be a case of the Nodific site in Cherakov. Mid-80s was located on a clear foreland of medium height dunes. Neighbouring ascending a path on a fallow land. Today it is covered by a young forest. No objects have been found on this site. Another case is the site of Chisova. It's known from the literature. The verification in mid-80s resulted in collecting more artefacts. Back then part of the site was covered by forest and remaining been a fallow land. Today a young mixed forest grows here including a great number of oaks. During the second visit of sandy clearing we found a few ceramics fragments dating to Bronze Age. Another object from this site. And these discoveries were made by surface. In the forest area studies almost integral tools as the leader analyzes. In our case we have comfort of using two open access visualizations. First is ISOC and another one is visualizations made for Campinas Wetland project. Even a view analysis showed a great number of World War II monuments and post-war military structures. Examples are shelters or trenches. But using a ladder we also have great visualizations show details of already known facilities. Like ammunition depot in Palmyra or Zamčesko's stronghold from 13th century. Also a number of mouths have been distinguished. Some of them probably barrels but without verification it's not possible to determine their functions. It is planned as I said before to recalculate the data obtained using a scanning especially for this project. Popularization as I mentioned previously is crucial to us. It is implemented during Saturday's excursion. Organized for all interest and participation. The idea is to show things that cannot be observed in the first glance as well as combined in nature. Related and historical, archeological problems. So far two events of this kind have been organized. And their claims deliberated chosen. There were two periods chronologically far from each other. First one is emesolithic and another was about interwar. The emesolithic excursion led around Bužova Góra Parabellikdjón. And similar in name people during what emesolithic archeology in the park was discussed. Including Palo.. Environment, fauna, house structures and their traces. As well as object dating to this period. We have also archery and flint mapping presentation. As the second team we have chosen ammunition depot in Palmyra active between 1929 and 1939. It's remaining unknown. But our idea was to show them as a group of dependent facilities to cooperate with us. We invited professor Zbigniew Tucholski from Institute of Science of History from Polish Academy of Science. An expert on railway and contemporary history. And Dr. Koloneł Krzysztof Gajku presented a course of the Tank Battle of Poczeka in 1939. The excursion route led around the railway and bank of ammunition depot against in Palmyra. In further future survey continuation is planned. With time we are planning to verification using method detector especially the Arias. With previously registered notification for example made by foresters. We have also intent to carry out test ranches or grills. Although this might be required consulting with the park staff responsible for environment protection. We should also be willing to cooperate with paleobotanics geologists and geomorphologists. Finally I would like to emphasize this excellent cooperation with Campinas National Park. Both research scientists and field workers who are keenly interested in our project. But also provide us with valuable information. Thank you for your attention.
