Moose cow and calf on Teal Lake

Today on my way to work I saw, for the first time, a Moose on the shoreline of Teal Lake. Not only that, but it was a cow Moose with a calf! To top it off, it was one of the Moose that have been collared by the Grand Portage Reservation Natural Resource Department! What a treat to see these animals today. The reservation has collared several Moose in order to track their movements over the course of two years and they will be using the collected data to help manage reservation lands for the benefit of Moose. I sat and watched this mother and child for about 10 minutes, and they barely moved. Just before I left the mother laid down in the grass and the calf followed suit. I wonder how long they stayed in this spot?
