This article describes the nature of including of Verkhoyansk-Chukotka area Verkhoyansk-Kolyma. Chukotka and South Anyui folded belts. It is shown, that formation these belts is not connected with the impulse of collision of Siberian and Arctic plates. The crumpling rocks of first of them into giant horizontal fold (Kolyma loop) is explained as a drift of Omolonsky massif along the border of Siberian craton. Sigma-form of Chukotka belt is cutting the structures Koluma loop is allow to interpret it as a lateral tectonic flow, which deforms Sigma as a result lock up its heads Anui-Novosibirsk part volcanic covers of Ohotsk-Chukotka belt. These data allow uncovering Verkhoyansk-Chukotka region as region of skirmish of structures of two lateral tectonic flowes of Polar province of Earth, composing on South Anyui-Pekulney transform fault.
