Narrative:

I was doing some flight training in the local area. The WX was marginal VFR. We climbed above the clouds to do the training. I could see the ground the entire time we were up. We were between the clouds. I was using an island in a lake for a reference to my location. When I got close to the island, it was not the one I thought it should be. I told the student to turn and descend as quickly as possible. The other way I realized I was in the wrong place was that I was listening to salt lake approach and I heard them call traffic to another aircraft. That traffic was me. What caused the problem was the low visibility. I could not see all of the lake and I assumed the island I saw was the right one. I do not know what could correct the situation. I made a mistake in navigation. The best way to prevent this from happening again, is for me to double-check my navigation.
