She still does exactly that. The markers are installed in the spring and removed in the fall, and then cached in safe locations along the river, otherwise they will be annihilated by the ice in the winter. You can easily find the caches on google earth. The Eckaloo and Dumit share the responsibility for the river; in general, one ship is responsible for the north half of the river, and the other responsible for the southern half. I believe the "divisional point" is Norman Wells. The ships are somewhat unique in the CCG fleet in that, as opposed to the normal 4 weeks on/4 off, they have one crew on board from spring breakup to freeze up, with up to 2 weeks leave in july/august. Leave is subject to relief availability.
