APPEC (Astroparticle Physics European Consortium) and its transnational partner JINR (Joint Institute for Nuclear Research) in Dubna, the Institute for Nuclear Research of the Russian Academy of Sciences together with the Lomonosov State University in Moscow, the Kabardino-Balkarian State University, and the Irkutsk State University are inviting astroparticle physicists and colleagues from neighboring fields to attend the Mount Elbrus Conference: from Deep Underground up to the Sky. The conference is continuing the series of APPEC-Russia events that started in 2016 with the Lake Baikal Three Messenger Conference and will provide the opportunity to discuss how to confine nature and underlying physical processes in the universe by making use of low background experiments in Deep Underground Laboratories, multi-messenger aspects related to these topics and the theory. Scientific results achieved with current astroparticle experiments will be shown and discussed together with upcoming experimental opportunities in Russia, Europe and worldwide. A detailed look shall also be taken on future requirements and potential synergies with other fields in science requiring a low background environment. This conference will offer an opportunity for the astroparticle physics community in Europe, Russia and worldwide to foster the cooperation on astroparticle physics in Deep Underground Laboratories. The conference will be held close to the Baksan Neutrino Observatory to feature its 50th anniversary in 2017.
