Solve tasks to find hidden Geo point coordinates

One of the smallest Latgali castle mounds – Markova castle mound has hidden itself on the coas of Daugava valley, surrounded by forests. The highest point is approximately 40m above Daugava level, which is why an impressive view of Daugava valley can be seen from the few vistas. On this nature trail from where an amazing view to picturesque Daugava arcs are opening, not far from Putāni brook there is a pole which marks the maximum water level for the designed HPP. 

Termination of Daugavpils HPP was not only an economical or aesthetic kind of issue – it was also one of the most significant movements of the time of awakening. Dainis Īvāns and Artūrs Snips article ”Thinking about Daugava destiny” in 17th October where a critique was expressed against the construction of Daugavpils HPP, started an sharp reaction about this issue. The main reason of Daugavpils HPP construction denial was definitely the fight about Daugava symbol as Latvian nations’ river of the faith and keeper of nations identity when the nation was not the auxiliary in its own land. During the period of Soviet Union decline, different environment protection questions received a political touch which was difficult to control, because theoretical environment questions were not connectable, with any political movement. 

D.Īvāns and A.Snips publication had the effect of an explosion – it caused an unexpectedly impressive response in television and press, and it also moved activity which was unusual for totalitarian system – a wide range signature collection against the plan of HPP. By 17th November, 1986 the editorial office received 93 letters in Latvian and Russian, signed by 2519 persons. Daugavpils power station construction usefulness in L&M October and November issues of 1986 is required by different national economy specialists from different branches. In 1987, collecting Latvia USSR and foreign scientist opinions about Daugavpils HPP project realisation economic and ecological consequences, it had to be admitted that Latvia and Belarus USSR would get more losses than benefits. Together there were around 30000 signatures collected against the construction of Daugavpils HPP. On 14th June, 1987, the project was terminated in Moscow, and the USSR Ministry Council stopped the excavation of the power station dam. The unbelievable had happened – thank to the society initiative, a 20 million rouble expensive project realisation which was included in USSR state plan, was terminated.
