Abstract Partisipants will examine: well preserved push and damp marginal moraines, subglacial interlobate ridge, and their geological structures (western part of the Kola Peninsula); landforms resulted from the glacial activity and displaying long-term glacial-erosion features and smaller scale landforms which in great detail record the process of the deglaciation of the area, as the glacial cirques, marginal moraines, end moraines, hummocky moraines, De Geer moraines, lateral meltwater channels, spillways, troughs, delta formations, ice-dammed lake shoreline, tor-formations (Khibiny and Lovosero Mountains); features of the glaciotectonic rising of the Kola Peninsula in the form of the isostatically raised beach ridges (coast of the White sea) and the seismodislocations caused by the neotectonic activity of the Baltic Shield (area of the Lake Imandra); the well known in the region interglacial section of marine sediments, which bear the evidences of the glacio-eustatic marine transgression (valley of the Varzuga River). Logistics Dates and location Timing: August 15 –August 20 Start location: Murmansk airport End location: Murmansk airport Travel arrangements The post-IGS excursion will start August 16 from Apatity. The Participants should arrive at the airport of Murmansk August 15 from where they will be taken to Apatity by bus (2.5 hours). The following routes to Murmansk are being considered. (A) Fly to St.Petersburg or Moscow and then from St.Petersburg or Moscow directly to Murmansk (most preferable, flights daily); (B) fly Oslo to Murmansk or fly Oslo to Tromsø and then Tromsø to Murmansk (flights four time a week). (C) Alternative direct fly from Moscow or St. Petersburg to Apatity (flights twice a week). Departure to Oslo August 20 by (A) Fly to St.Petersburg and then from St.Petersburg to Oslo (most preferable, flights daily); (B) Fly from Murmansk to Oslo or Murmansk to Tromsø and then Tromsø to Oslo (4 flights a week). Accommodation Hotel accommodations are planned in Apatity and Kandalaksha. Blocks of single and double rooms will be reserved for participants, no additional arrangements needed. In Varsuga village accommodation is planned in a tourist camping on the beautiful Varzuga River shore. <strong>Field</strong> logistics Transport: In order to reach all geological objects situated 50 – 300 km far from Apatity, the trip will be run with 20-seat off-road bus-like truck with experienced geologist driver. Besides, such truck is the only vehicle available for the localities which we are going to visit during excursion. For trip from Murmansk Airport to Apatity (200 km from Apatity) and back we arranged comfortable bus. 3
